Not only were they the first documented rock samples returned from an extra-terrestrial body, but they were also the subjects of the first concentrated effort by the world's scientific community to fully characterize a suite of rock samples. With the return of the Apollo II samples, a team of scientists, the Preliminary Examination Team (PET)*, was formed and given the task of characterizing the rocks and soils. Their task was to sort, classify and describe the samples so "that they could be allocated to an eager group of principal investigators prior to the return of Apollo 12. Five weeks after the samples were received in the LRL, the first Apollo II Sample Catalogue was compiled and published. In June of 1975,, the Apollo II Re-examination Team was formed to compile data for a revised Apollo II Sample Information Catalogue. The basic aim of this group was to re-examine the Apollo II samples applying the experience gained during five subsequent missions, document them, and publish this information along with historical, chemical and age data in a revised catalogue. The first step in the re-examination process was a thorough search of all available documentation pertaining to the early processing of the samples. Because of the short time allotted to Preliminary Examination, this type of information was sketchy, at best, and for the most part, non-existent. What information could be obtained was summarized into a sample history for each generic sample. During this part of the re-examination process any contaminating conditions that were peculiar to a certain rock or group of rocks which had been documented or could be inferred, was compiled. Next, a listing compiled from chemical data so that major of the chemical and age data for each generic sample was analyses published as of June 1976. In instances where no was available, an allocation from the sample was scheduled element analyses could be obtained. Pristine samples were examined in a nitrogen processing cabinet where they were dusted, photographed (one to six views) and described with a binocular microscope. An attempt was made to reconstruct the original rock (or a part of it) from the remaining pristine pieces and existing documentation, and to locate these pieces on photographs taken by the PET before splitting. In some cases this was successful; in other cases, the low percentage of remaining sample and the lack of rock subdivision photography made reconstruction of the rock pieces impossible. Because the photographs taken *For definitions of terms and acronyms, see Appendix A. during the PET examinations "fitted" into the original confidence. were of dusty rocks, rock photographs with few pieces could be any reasonable degree of All rocks larger than 5gm. currently stored in the Returned Sample Laboratory were examined in the same manner as above.

The crew of Apollo II consisted of Neil A. Armstrong, Commander; Michael Collins, Command Module Pilot; and Edwin E. Aldrin, Jr., Lunar Module Pilot. The following is a summary of the Apollo II mission. More detailed information may be found in the Apollo II Mission Report (NASA SP-238). The space vehicle was launched from Kennedy Space Center, Florida, at 08:32:00 a.m.,e.s.t., July 16, 1969, and was inserted into lunar orbit approximately 76 hours later. After a rest period, Armstrong and Aldrin entered the lunar module to prepare for descent. The command and service modules were then separated from the lunar module (Eagle). Descent orbit insertion was performed at approximately 1 I/2 hours after separation and power descent to the lunar surface began approximately 1 hour later. The Eagle landed in the Sea of Tranquility at 3:17 p.m.,e.s.t., July 20 (Fig. I). The landing site was on a gently sloping mare just west of a young ray crater approximately 200 meters in diameter (Fig. 2). During the first 2 hours on the surface, the astronauts performed a postlanding check-out of all lunar module systems, ate their first meal on the moon and elected to perform the surface operations earlier than planned. Armstrong egressed through the forward hatch and deployed the Modularized Equipment Stowage Assembly (MESA), located in the descent stage. A camera in the MESA provided live television coverage of Armstrong descending the ladder to the surface, with first contact made at 9:56 p.m.,e.s.t., July 20, 1969. Aldrin followed soon thereafter, and both crewmen used the initial period on the surface to become used to the reduced gravity conditions. The Contingency Sample was taken from the surface, and a television camera was deployed so that most of the lunar module was included in the field of view (Fig. 2). The crewmen took numerous photographs, erected the U.S. flag, and deployed the scientific experiments, which included a solar wind detector, a passive seismometer, and a laser reflector. Aldrin spent considerable time evaluating his ability to operate and move about, and despite the limitations imposed by the pressurized suit, he was able to move rapidly and with confidence. Approximately 20 kilograms of rock and particulate material were collected to be returned to earth. The crew had spent a total of 2 hours and 14 minutes exploration time on the lunar surface. The ascent preparation was conducted, and the ascent stage lifted off the surface at 1:02 p.m.,e.s.t., July 21. After a rendezvous sequence, the two spacecrafts were docked at 5:02 p.m.,e.s.t., July 21. Following transfer of the crewmen, the ascent stage was jettisoned, and the command and service module was prepared for trans-earth injection.

Hornet and were transferred into the Mobile Quarantine Facility (MQF). Inside the MQF the sample containers were enclosed in plastic bags, to insure biological containment, and were passed to the outside of the MQF through a surface sterilization procedure and lock. The samples were flown to Jonston Island where they were transferred on board two separate jet aircrafts for transport to the Manned Spacecraft Center and the Lunar Receiving Laboratory (LRL). One of the sample return containers, the second box collected (documented sample) was on board the first aircraft to arrive at Ellington Air Force Base, Houston, Texas. The sample was carried to the Lunar Receiving Laboratory in a motor van, and was introduced into the Crew Reception Area of the LRL. The second aircraft arrived at Ellington Air Force Base a few hours later with the first sample return container filled on the lunar surface (bulk sample) and with the contingency sample. These samples were also brought to the LRL by motor van and introduced into the Crew Reception Area. SAMPLE COLLECTING TOOLS AND CONTAINERS The Apollo II crewmembers used the following sample-collection tools and containers to obtain samples of the lunar surface. The tools were designed of material rugged enough to do the job, yet light enough to conform to the weight and space limitations of the lunar module stowage area. The limitations imposed on the movements of a crewman while wearing a pressurized space suit also had to be considered; therefore, the tools were designed with quick-disconnect fittings to enable the crewman to attach or detach components with a minimum of difficulty. Knurled or roughened areas were provided on many tools to improve the crewman's grasp. Prime consideration was given to the selection of the metals and lubricants used in the construction of the tools to avoid elements and isotopes that might contribute to serious geochemical contamination (such as lead, strontium, etc.). The two Apollo lunar sample return containers (ALSRC, Fig. 3) were portable, sealable aluminum containers; each container weighed approximately 6.8 kilograms, _easured 20.3x26.7x44.5 centimeters and had a capacity of 0.023 cubic meters. They were lined with York stainless steel mesh and Teflon. Prior to the lunar landing, these containers housed the core tubes and other related equipment. On the lunar surface, the astronauts opened, filled, and closed the containers. Three seals on the hinged lids (one of indium and two of Viton) preserved the samples in the vacuum environment during transportation back to the Lunar Receiving Laboratory. Upon return to the LRL, readings were taken to determine the atmospheric pressure inside the sample container. Both ALSRC's had internal pressures of was maintained during earth. 170 microns; proof a substantial negative transfer of samples from the lunar surface pressure back to The hammer (Fig. 4) was made of tool steel suitable for impact use. The head was coated with vacuum-deposited aluminum to minimize solar heating. The handle was offset slightly so that the astronaut could strike a square blow despite the encumbrance of his pressurized space suit. The end of the hammerhead opposite the striking surface was shaped for use as a pick or chisel; with the extension handle attached, it could be used solely for driving the core tubes into the surface by striking the end of the extension handle. The tongs (Fig. 5) were made of anodized aluminum (No. 606 T6) and were used to retrieve samples of pebble size and larger. This tool consisted of a set of opposed, spring-loaded fingers attached to a 66-centimeter handle. The tongs were operated by squeezing the handles to actuate the cable that opened the fingers. The extension handle (Fig. 6) was used to increase the astronaut's reach by adding 58.4 centimeters of handle length to various tools. The lower end of the extension handle had a quick-disconnect mount and lock for tool attachment. The upper end was fitted with a sliding tee handle to facilitate any torquing operations. The large scoop (Fig. 7) was made of anodized aluminum (No. 6061T6) and had an appearance similar to the bucket of a power shovel. The scoop and its handle measured 39.4 centimeters, and could be extended an additional 58.4 centimeters using the extension handle. The large scoop was used in the lunar extravehicular activity to collect the bulk sample. Two core tubes (Fig. 8) were made of anodized aluminum (No. 6061 T6) and were used to obtain samples from the lunar surface in a manner such that any possible near-surface stratigraphy would be preserved. The core tubes are 41.3 centimeters long and would be attached to the extension handle. Two tubes, each containing a sample, were capped and placed in the documented sample return container. The contingency sample container (Fig. 9) consisted of a small Teflon bag, resembling an oversized sandwich bag, and a jointed aluminum handle approximately 84.5 centimeters long in its fixed extended position. The bag measured 5.2x12.7x17.8 centimeters. The contingency sample container was used to obtain a lunar sample during the early stages of the extravehicular activity. This sample was intended to provide at least a small amount of lunar material for return to earth if it were necessary to terminate the surface portion of the mission early. Fig. 3: Sample Return Container with Rocks (ALSRC) lO Figure4 :Hammer Figure 5:Tongs II Figure6 :Extensionhandle Figure 7:Large scoop 12 Fig. 8: Core Tubes 13 Fig. 9: Contingency Sampler 14 SAMPLE COLLECTION AND RETURN The contingency sample was taken in full view of the sequence camera just outside Quad IV of the lunar module (Fig. 2) and took about 3 minutes 35 seconds to collect. The sample bag was filled with two scoops for a total of approximately 1 kilogram. The areas scooped have been accurately located on a pre-extravehicular lunar module window photograph from study of the sequence film data. Both scoops included small rock fragments visible on the surface from the lunar module windows prior to sampling. The handle of the scoop apparatus was shoved by Armstrong 15 to 20 centimeters into the surface very near the area of the first contingency scoop. The ease of penetration in this place may be, in part, a result of disturbance to the regolith by scooping. The contingency sample container was stowed in a Beta-cloth bag during the return trip and accompanied the astronauts to the Crew Reception Area of the LRL. The bulk sample consisted of 15 kg of rock and soil, loaded into one of the ALSRC's. A total of 14 minutes was required by Armstrong to collect the bulk sample. Five minutes was spent sealing the box. Armstrong went out of the television field of view three times during bulk sampling, twice to the left for a total of 1 minute II seconds and once to the right for 35 seconds. Seventeen or 18 scoop motions were made in full view of the television camera, and at least five were made within the field view of the sequence camera. The total number of scoops was 22 or 23. Nine trips back to the MESA were made to empty the scoop. The average number of scoop motions to fill the scoop was two and one-half. The ALSRC was sealed on the lunar surface and accompanied the astronauts into the MQF aboard the U.S.S. Hornet. The bulk sample ALSRC was flown from the MQF to Hawaii where it was transferred to a range instrumentation aircraft for transfer to Houston. The two core-tube samples were 3oth were taken in the vicinity collected by Aldrin in 5 minutes 50 seconds. of the Solar Wind Composition Experiment. The documented sample consisted of approximately 20 selected, but unphotographed, grab samples (about 6 kilograms) collected by Armstrong in the final three and one-half minutes of the extra-vehicular activity. Collection of these specimens was made out to a distance of I0 to 15 meters in the area south of the +Z-axis footpod near the east rim of the large double crater. Armstrong was out of the television _eld of view to the west 25 percent of the time during this activity. The two core the container tubes were single-layered was sealed on the lunar in the surface.

EARLY PROCESSING HISTORY The Documented Sample ALSRC was transferred from the Crew Reception Area to the Sample Laboratory on July 25 and introduced into the atmospheric decontamination cabinetry system. The sealed documented sample box entered the F-201 vacuum system July 26, with the F-201 chamber pressure at approximately 7 x 10-6 torr. The box was opened after an unsuccessful attempt was made to analyze the atmosphere in the box by mass spectrometry through a probe inserted in the box end. The Lunar Sample Preliminary Examination Team made their initial inspection of the box contents after the Teflon bag containing the samples had been cut and peeled back. (Fig. 3) A few hours later, the first rock, sample 10003, was selected for gamma counting in the Radiation Counting Laboratory (RCL). See Table 2 for a description of the contents of the Documented Sample ALSRC. The two core tubes and selected fines were next transferred logical Preparation Laboratory. Later, one of the core sample 10004, was opened and inspected and found to have and the follower improperly inserted, but the sample was detailed information concerning the core samples may be Lunar Core Catalogue (Duke and Nagle, 1974). to the Biotube samples, a missing cap intact. More found in the The Gas Reaction Cell (GRC) was intended to be used to determine whether violent reactions occurred when lunar material was exposed to various atmospheric gases. The cell was transferred to PCTL, but inspection of the cell in the PCTL indicated that the port cover had been broken during handling, exposing the sample to nitrogen. The remaining portion of the gas reaction tests (exposure to oxygen, carbon dioxide and water vapor) was performed, and there was no apparent change in the sample. During subsequent sample description and splitting operations in F-201, a leak developed rapidly in one of the gloves, and the interstitial glove pressure went to atmospheric, but the pressure in F-201 is believed not to have risen above approximately 2 centimeters of mercury. Samples in F-201 at that time were 10017, 10018, 10019, and 10020. Some other samples, not yet numbered were in a vacuum beaker that had two bolts loose, and other samples were safely inside vacuum-sealed beakers that were properly sealed. It was necessary to sterilize the entire system with dry heat in order to replace the damaged gloves without violating the biological containment. After the gloves were replaced, the system was pumped down to operating pressures and processing of the samples from the documented box was continued. Sample 10020 was removed from the vacuum system after sterilization, placed in a glass vacuum jar, and 16 placed where it Team and visitors. could be viewed by the Lunar Sample Analysis Planning The Bulk Sample, ALSRC (#1003), contained most of the rocks and fines returned from the Apollo II mission. (See Table 2) This sample box was transferred into the first vacuum lock of the F-201 vacuum system, but after the glove accident (See p.15 ) it was decided to use the nitrogen cabinets in the Biological Preparation Laboratory for the opening and processing of the samples from the bulk box. The bulk box was transferred into the nitrogen atmosphere cabinets in the Biological Preparation Laboratory on August 2. The bulk box samples were examined, described, photographed, and chipped in the Biological Preparation Laboratory, and chips were transferred to the PCTL for more detailed description. Most of the samples from the bulk box were maintained in the nitrogen cabinetry in the Biological Preparation Laboratory until the end of sample quarantine. The contingency sample was transferred from the Crew Reception Area to the PCTL on July 27, where it was placed inside the nitrogen atmosphere cabinetry. The contingency sample was opened, and an initial inspection of the sample was made. The largest rock from the contingency sample, sample 10021, was transferred to the RCL. All rocks and fragments greater than 1 centimeter in size were removed from the contingency sample, and given sample numbers (See Table 2). Most of the contingency sample remained within the nitrogen atmosphere of the PCTL cabinetry until the end of sample quarantine. However, the contingency sample container was exposed to cabin atmosphere during storage and transportation back to earth. It was not opened, however. 17 Generic TABLE I - APOLLO II Sample Listings with Original Weights Returned Container ALSRC 1004 ALSRC 1003 ALSRC 1004 ALSRC 1004 ALSRC 1004 ALSRC 1004 ALSRC 1004 Cont.

The or 10-6 torr) vacuum. Upon entering the atmospheric sterilization cabinets, the ALSRC was subjected to a nitrogen purge, then washed twice in a peracetic acid solution and rinsed twice with deionized water. This was repeated before the container was dried with hot nitrogen. This procedure was repeated for items leaving the system. Upon removal from the ALSRC container, samples were weighed, brushed off, photographed, placed in vacuum containers and stored in the sample carousel. The carousel was kept closed off from the main chamber, to prevent contamination of all samples during a possible glove rupture. The sample carousel could be detached from the glove chamber, and was intended to be kept under its own vacuum indefinitely. During the processing of the samples, a leak developed in one of the gloves causing the interstitial glove to go to atmospheric pressure. However, the pressure inside F-201 was believed not to have risen above 2 cm. of mercury. Samples in F-201 at the time were 10017, 10018, 10019, and 10020.

PHYSICAL CHEMICAL TESTING LABORATORY (PCTL) PCTL was used for the petrographic study and chemical analyses of small subsamples. It consisted of six nitrogen atmosphere processing cabinets that housed an X-ray diffractometer, X-ray fluorescence analysis unit, an optical ommision spectrograph, and three petrographic microscopes. There was little control over extraneous materials, since only small samples were handled in this cabinet system and materials such as refractive index oils were kept inside the cabinets. 23 NA$A-$-67-692 RESIDUAL GAS CELLS PORTS OSCOPE PORT OPERATOR VIEWING PORTS VACUUM GLOVE CHAMBER, F-201 PORTS MONO RAiL 2o2PORT 3VE PORTS Fig. I0: F-201 System NASA S-67-6842 PRIMARY LRL VACUUM SYSTEM _ SAMPLE / _ "_ _ _ TOOL "_CAROUSE_ / VACUUM _/\ ,_'_ _ANSFER LOCKS_ _=:_ _r_ _ __ _ / o___ _. jj _ u_ _ ULTRA'HIGH _ I j_ _ ____-_u _VACU_ VACUUM CHAMBER /I " ATMOSPHERIC GLOVE CHAMBER _._ STERILIZATIONCABINET \ Fig. 11: F-201 System 24 NASA-S-67-693 BIOLOGICAL FLORESCENT CABINETRY / FILTER CANISTER LIGHTS_ _j__THERMOSTAT_ _FILTER CONTROLS VlEWIN_ )lJ/lt_d'/ )_1 _'/ ));Jl_ II, PORTS STERILIZER FREEZER ----1 SINK-_/ r i r V DECON BATH Fig. 12: Bio-Prep Lab NASA-S-G?- [230-CEB PHYSICAL-CHEMICAL TRANSFER ,-GLOVE STATIONS LOCK_ \ TEST LAB SPECTOGRAPH_7 --TARC - \ STAND/J // 1 \REACTIONGRAPH _ _ ' ' STATIONS Fig. 13: Physical-Ohemica] Test Lab. 25 At first, sample splits removed from rocks in the F-201 and Bio-Prep Labs, were examined and analyzed in PCTL. Later in the mission processing, the Contingency Sample was transferred to PCTL for initial photography and description. Early principal investigator allocations were made in PCTL. SAMPLE PACKAGING LABORATORY (SPL) The Sample Packaging Laboratory was set up during samples for distribution to Principal Investigators examination work was completed.

All samples processed in this lab are done so in a nitrogen atmosphere. Any sample placed in storage or sent to a principal investigator must have three levels of protection. This usually constitutes a hard container, and two teflon bags, all three sealed in nitrogen. Rock sawing is presently accomplished using a cleaned, nitrogen atmosphere bandsaw as opposed to an open-air wiresaw. This laboratory has been used to prepare all pristine Apollo II samples subsequent to the initial mission processing. RETURNED SAMPLE PROCESSING LABORATORY (RSPL) RSPL is set up to process samples that have been returned by principal investigators. Most samples are examined and repackaged in air on a laminar flow bench. All samples must have three levels of protection before storage. Some samples in RSPL are processed in nitrogen glove cabinets. are usually returned display samples, which are candidates for to SSPL pristine storage.

The landing site is 41.5 kilometers north-northeast of the eastern promontory of the Kant Plateau, the nearest highland region. Apollo II landed approximately 25 kilometers south-southeast of the Surveyor V Spacecraft landing site and 68 kilometers southwest of the crater formed by the Ranger VIII impact. The southern part of Mare Tranquillitatis is crossed by relatively faint north-northwest trending rays, and prominent secondary craters associated with the crater Theophilus, 420 kilometers southeast of the landing site. About 15 kilometers west of the landing site is a fairly prominent north-northeast trending ray. The crater with which this ray is associated is not definitely known, but it may be Alfraganus, 160 kilometers to the southwest, or Tycho, about 1500 kilometers to the southwest. Neither the north-northeast nor any of the north-northwest trending rays cross the landing site. They are sufficiently close, however, that it is possible that some material from Theophilus, Alfraganus, or Tycho occurs in the vicinity of the lunar module. Other distant craters, especially the crater Moltke which lies 40 kilometers to the southeast, may also be the source of fragments lying near the lunar module. Some potential distant sources of fragments are in the highlands and some in the maria. A hill of terra material protrudes above the mare surface 52 kilometers east-southeast of the landing site. This suggests that the mare material is very thin in this region, perhaps no more than a few hundred meters thick. Craters more than a kilometer across, such as Sabine D and Sabine E, may have been excavated partly in pre-mare rocks. Pre-mare rock fragments ejected from these craters may occur in the vicinity of the lunar module. 27 The major topographic features in the landing area are large craters a few hundred meters across, four of which are broad subdued features and the fifth is West Crater, located 400 meters east of the landing point. West Crater is a sharp-rimmed, rayed crater about 180 meters in diameter and 30 meters deep with a blocky-ejecta apron extending almost symetrically outward to a distance of about 250 meters. Rays of blocky ejecta extend further west, probably past the landing site. Near the lunar module, the surface is pock-marked by numerous small craters and strewn with fragmental debris, part of which may have been derived from West Crater. A boulder field north of the lunar module (described by the crew and shown in photographs taken by the crew) is probably part of a blocky ray. All of the craters in the immediate vicinity of the lunar module have rims and floors of relatively fine-grained material and appear to be excavated entirely in the regolith. A pile of blocks and coarse rubble forms a peak on the floor of the 33-meter crater east of the lunar module but the walls and rim of this crater have the same texture as the regolith elsewhere. West Crater is about 30 meters deep and has a coarse blocky rim. Among the smaller craters, both sharp raised-rim craters and relatively subdued craters are common. They range in size from a few centimeters to 20 meters. A slightly subdued, raised-rim crater (Armstrong's 70- to 80- foot crater) 33 meters in diameter and 4 meters deep occurs about 60 meters east of the lunar module, and a double crater (Armstrong's doublet), about 12 meters long and 6 meters wide, lies I0 meters southwest of the lunar module at 260 ° azimuth. The walls and floors of most of the craters are smooth and uninterrupted by either outcrops or conspicuous stratification. There are rocks present in the 33-meter crater that are larger than any of those seen on the surface in the vicinity of the lunar module. With this exception, there is no apparent correlation between the location of blocks and the smaller craters near the lunar module. The surface of the mare near the landing site is unusually rough. Television pictures show a greater abundance of coarse fragmental debris than at any of the four Surveyor landing sites on the maria except that of Surveyor I. It is likely that the observed fragments and the samples returned to earth have been derived from varying depths beneath the original mare surface and have had widely different histories of exposure on the lunar surface. The lunar module footpads penetrated a maximum of 7 to 8 centimeters. The astronaut's boots left prints generally from 3 millimeters to 2 to 3 centimeters deep. As the astronauts walked, they noted that their boot tread was preserved in their footprints, and that angles of 70 degrees were main- 28 tained in the print walls. The surface, to break into slabs, cracking out as far the edge of footprints. where disturbed by walking, tended as 12 to 15 centimeters from The regolith is weak and relatively easily trenched to depths of several centimeters. Surface material was easily dislodged by kicking. Before the lunar module landed, at an altitude somewhat less than 30 meters, dust was observed moving away from the center of the descent-propulsion-system blast. When the flagpole and drive tubes were pressed into the surface, they penetrated with ease to I0 to 12 centimeters. However, at that depth the regolith was not strong enough to hold the core tubes upright. A hammer was needed to drive them to depths of 15 to 20 centimeters.* At places, rocks were encountered by the scoop and by the various tubes and rods pressed into the subsurface. Coarse fragments in the vicinity of the lunar module exhibited a wide variety of shapes and were embedded in varying degrees in the fine mat of the regolith (Armstrong, comment). Armstrong took time during the television panorama to point out several rocks west of the television camera, one of which was tabular and standing on edge, protruding 30 centimeters above the surface. During the postmission debriefing, Armstrong described another rock as resembling a distributor cap. When dislodged, the cap was found to be the exposed top of a much larger rock, the buried part of which was much larger and more angular in form. Strewn fields of angular blocks, many more than one-half meter long occur north and west of the lunar module. In general, the rocks collected tended to be rounded on top and flat or angular on the bottom. The strength of rock fragments ranged from friable to hard, and was difficult for the crew in some cases to distinguish aggregates or clods of fine debris from rocks. Armstrong suggested that West Crater was the source for these boulder fields and may be the source for any of the rocks in the immediate vicinity of the lunar module. SAMPLE SURFACE DOCUMENTATION An attempt was made by PET members to locate and document Apollo II samples in EVA photographs. However, because of the time constraints placed on the astronauts, very few photographs were taken of samples they lay on the lunar surface. Subsequently, tentative identification some samples were made from photographs taken from the LEM viewports. *It was subsequently determined the jamming of material in the designed for greater penetration. that core. the design of the core bit The bits were subsequently as of led to re- 29 The Apollo II preliminary science report (NASA SP-214) data and photographs were available, but offers little of documented samples as they lay on the lunar surface. PETROLOGY A total sample of 48 rocks were returned return containers. Pieces documents what concrete proof along with fines material in the smaller than lOn_n are classified three as fines. SURFACE FEATURES During preliminary examination one surface feature of the rocks that was most noticeable was the rounding of one or more edges and corners. Many of the rocks had one flat surface, with the remaining sides rounded. This rounding appeared to be more pronounced in the softer, more friable breccias than in the crystalline rocks (LSPET, 1969). Two other types of surface features occur on the Apollo II rocks. These are glass-lined pits and glassy spatters not necessarily associated with pits. Most glass-lined pits are less than one millimeter in diameter, but they have been found as large as 4mm (I0063,1). Impacts that would produce the larger pits usually break the rocks apart and the pits are not preserved. The rocks generally show pitting in the rounded surfaces but not on the flat sides. The glass lining the pits is bright-reflecting and commonly uneven and botryoidal. The pits are generally surrounded by whitish haloes which are at least partially attributable to intense microfracturing of minerals. This whitening does not appear to penetrate more than Imm below the surface of the rock (LSPET, 1969) and tends to give the surfaces of the crystalline rocks a lighter color than the interiors. In addition to glassy pits, thin glass crusts occur that appear to be the result of spattering. These crusts are generally less than Imm thick. Taken together, these features make up what is known as patina. BASALTS All of the basalts returned are volcanic in origin and probably represent surface or near surface lavas. The term "volcanic" carries no connotation regarding impact generated or triggered volcanism versus volcanism in the common terrestrial sense. The rocks contain pyrogenic mineral assemblages and gas cavities suggesting that they crystallized from melts. The major minerals can be assigned 3O to known rock-forming mineral groups. The unique chemistry of the magmas has resulted in mineral ratios different from known terrestrial volcanic liquids, yet not significantly different (at least in the major elements) from some terrestrial cumulates (LSPET, 1969). The Preliminary Examination Team (LSPET, 1969) divided the crystalline rocks into fine-grained (Type A) and coarse-grained (Type B). Grain sizes of Type A rocks (fine-grained) range from 0.05 to 0.2 mm. A typical mode (10017) is pyroxene, 44%; plagioclase, 24%; opaques (mainly ilmenite), 24%; mesostasis, 8%. Grain sizes of Type B rocks (coarse-grained) vary from 0.2 to 0.3 mm. A typical mode (10044) is pyroxene, 47%; plagioclase, 34%; opaques, 12%; cristobalite, 3%; and, mesostasis, 4%. James and Jackson (1970) and James and Wright (1972) have classified the crystalline rocks as ilmenite basal ts following the rather loose definition of basalt by Holmes (1920). They divided these further, on the basis of texture, into three sub-groups. These are, I) intersertal; 2) fine-grained ophitic; and, 3) medium-grained ophitic. Basically, the intersertal basalts correspond to some of the LSPET (1969) fine-grained (Type A) rocks. The fine-grained ophitic basalts correspond to the remainder of the fine-grained rocks. The medium-grained ophitic basalts correspond to the coarse-grained (Type B) rocks. Tera et al. (1970) and others have classified the crystalline rocks chemically on the basis of potassium content. Generally, the high-k (>0.20%K) rocks have intersertal textures and the low-k (<0.20%K) have ophitic textures. The Apollo II Re-examination Team classified the crystalline rocks according to the following scheme: All crystalline rocks observed were called basalts. When the accessory materials olivine or cristobalite were found in the samples, respective modifiers were prefixed (i.e. cristobalite basalt, olivine basalt). If neither was observed, the presence of abundant vesicles was noted (vesicular basalt). If a particular sample was non-vesicular, the grain size (fine or medium) was used as a modifier. A summary of Table 3. BRECCIAS The breccia samples returned by Apollo II are mixtures of fragments, various kinds of rocks, minerals, and glass, and are grey to dark grey in color. Most breccias are fine-grained, with fragments smaller than 1 cm in diameter. the Apollo II crystalline rock classifications is shown in 31 0--0-_ _1 "-_- ._1 -r- "_ -r- 0 0 0 0"_ ._1 .,_1 .__1_J -i- O-r0 0-_--_--_,_1 "_r_ ._J __1 -r" -_- -i- 0 _ _ _ ..... _ _ _ o OC_O00000C=;O0 00000000000 _00 O00 O00000 O0 C) O C_C) ¢_ 32 The term "matrix" refers to material that is too fine-grained to be resolved by whatever optical means are employed, be it a petrographic microscope, a binocular microscope or the unaided eye. Clasts are those fragments that can be resolved from the matrix through differences in color, texture or composition. The types and abundances of clasts found in the Apollo II breccias are summarized in Table 4. It can be seen from Table 4 that many clast types (white, brown, salt & pepper, brown & white) are dissimilar to the crystalline rocks collected at the Apollo II site and probably represent ejecta from distant impact sides. The matrix consists largely of glass particles and mineral fragments. Much of the glass has undergone some devitrification, which gives the matrix an overall turbid appearance in thin section. Because the chemical composition of the soils and breccias are similar (but not identical) it was assumed by LSPET (1969) that the breccias were some sort of lithified soil, and lithification by shock was put forward as a mechanism. This mechanism was favored by King et al. (1970), Mason et al. (1970), Quaide and Bunch (1970), Shoemaker et al. (1970), Wood et al. (1970). Other investigations have proposed lithification by thermal welding [Smith et al. (1970); Duke et al. (1970); McKay et al. (1970); and McKay and Morrison (1971)]. A third hypothesis proposed by Chao et al. (1971) suggests that breccias are formed by low level shock compaction of soil located some distance from the point of impact and near the base of the regolith. SOILS Soil samples Samples, all were obtained from the Contingency, Documented and Bulk of which were taken within 30m of the lunar module (Fig. 2). The Contingency Samples soils were collected along with the rocks using the special Contingency Sampler (Fig. 9), in which rocks and soils were collected simultaneously by scooping. Except for the drive tube samples, the only soil present in the Documented Sample was what adhered to the rocks. This soil was admixed with material produced by the crumbling and spalling of the rocks. The soils present in the Bulk Sample were collected by scooping into the regolith using the large scoop (Fig. 7). During Preliminary Examination, fines samples Documented, Bulk and Core samples were sieved as cumulative-weight percent curve (Fig. 14). from the Contingency, and the results plotted Since apparently a scoop was not used in collection of the documented samples, the fines (I0011) with the rocks probably consist of a mixture of soil that adhered to the rocks with material abraided from the rocks in transit, especially from the friable breccias.

These occur as black to grey basalt fragments with densities of greater than 3.32 gm/cm2 (Heiken, 1975). Mineralogically and textureally these fragments are similar to the basalts collected at the Apollo II landing site (LSPET, 1969). Most of the mineral fragments found in the soils are comminution products of the basalts: ilmenite, pyroxene, plagioclase, olivine and chrome spinel (Heiken, 1975). Small amounts of cristobalite and alkali feldspar have also been reported (Agrell et al., 1970; VonEngelhardt et al., 1970.) Breccia fragments. These occur as tabular to equant, subrounded to subangular fragments with densities of 2.9-3.1 gm/cm3 (Heiken, 1975). The breccia fragments are composed of basalt, glass, mineral and previous breccia fragments (LSPET, 1969). It has been proposed by Agrell et al. (1970), Chao et al. (1971), and others that the breccia fragments are a result of soil lithification, but there is not a direct correspondence of soil modes to breccia modes (Duke et al., 1970). It has been postulated by Heiken (1975) that the breccias are most probably a mixture of freshly comminuted rock and soil from impact craters. Glass spheres, l-mm to 3-mm-diameter glass spheres make up a minor (I-5%) but thoroughly studied soil constituent. Most are spherical, but some occur in ovoid to dumbbell shapes. Various colors are exhibited with a predominance of pale amber (2.2-2.6 gm/cm3), dark amber (2.7-3.2 gm/cm3), red brown (3.0-3.32 gm/cm3), and pale yellow, pale green or colorless (2.2-2.6 gm/cm3) spheres (Duke et al., 1970; Agrell et al., 1970). Many spheres are devitrified; some of the larger spheres have the larger vesicles. Many spheres exhibit flare patterns. Some sphere surfaces are coated with imbedded particulate matter or spattered droplets of glass, Fe, Fe-Ni and troilite (McKay et al., 1970; Agrell et al., 1970) and some surfaces show evidence of micro-meteorite impacts (zap pits). Microanorthositic fragments. Small, angular fragments of plagioclase (Angs) with small ilmenite and rutile inclusions are described by Agrell et al., (1970) and Wood et al., (1970). 2) 3) 4) 35 The origin for these fragments mare regions with anorthite-rich 5) may be the lunar highlands or basalt flows (Heiken, 1975). Meteoritic material. Only a trace of identifiable meteoritic material has been identified in the Apollo II soils. Rare metal grains, some with microcratered surfaces, are present. They are composed of some single-crystal kamacite and taenite and a hexahedrite with kamacite and zoned taenite (Agrell et.al., 1970; Goldstein et al., 1970). There is agreement among investigators that the Apollo II soils were formed by meteorite con_ninution of fine-grained basalt and coherent breccia. Agglutinate grains and most glassy particles were formed by melting of rock and soil by impact processes. It is possible that some of the glass spheres have a pyroclastic origin, but they are very minor soil constituents (Heiken, 1975). CORES (from LSPET, 1969) Two core samples, each 2 centimeters in diameter, were returned: core tube 1 (10005) contained I0 centimeters, and core tube 2 (10004) contained 13.5 centimeters of material. The cores are composed predominantly of particles with diameters from 1 millimeter to 30 micrometers, with admixed angular rock fragments, crystal fragments, glass spherules, and aggregates of glass and lithic fragments in the coarser-sized fraction. Both the material in the tubes and the fines in general are medium to dark grey with a tinge of brown. When prodded with a small spatula, the material disintegrates particle by particle or forms extremely fragile ephemeral units of subangular blocky shapes. Neither core sample shows obvious grain-size stratification. The core from tube 2 has a slightly lighter zone about 6 centimeters from the top surface which is 2 to 5 millimeters thick with a sharp upper boundary and a gradational lower boundary. This lighter zone is not megascopically different in grain size or texture from the dark material. MINERALOGY Clinopyroxene -Clinopyroxene occurs in all of the rocks examined. The most widespread variety is cinnamon brown to resin brown in hand specimens and pale reddish brown to pinkish brown to nearly colorless in thin section. Little or no pleochroism is associated with the crystals. The habit of clinopyroxene in the crystalline rocks is generally stubby prismatic or anhedral, with some sheaf-like intergrowths with feldspar also being present. Some crystals are strongly zoned from the center outward as indicated in increasing positive optic angle from near 0° to near 50 ° together with increasing refractive index and intensity of color. 36 Rare pale yellow crystals of interstitial crystals to the several of the more coarsely pyroxferrite occur pyroxene crystals, crystalline rocks. as overgrowths and in cavities and in Olivine - Olivine from Fo6s to Fo?s is a stituent of several of the finer crystalline cally as crystal fragments in the breccias greenish yellow in the crystalline rocks greenish yellow through honey yellow and and dust. Much of the olivine occurs as crystals. subordinate phenocrysitic conrocks, and occurs sporadiand dust. It is clear pale but may range in color from orange yellow in the breccias anhedral cores in pyroxene Plagioclase - Plagioclase is likewise widespread but generally subordinate in amounts to the ferromagnesian minerals. It is calcic, mostly between An?0 and Ang0, with some compositional zoning in some rocks. The habit is commonly tabular and plate-shaped, with lamellar twinning parallel and transverse to the plates. Interstitial, anhedral, poorly twinned crystals also occur in many of the basaltic rocks. llmenite - llmenite is present in relatively large amounts in the crystalline rocks. It occurs as lathes and well-formed skeletal crystals, llmenite is also common in the breccias and soil as a constituent of the lithic fragments and as isolated crystal fragments. Many of the larger crystals show exsolution of chromite, rutile and many have armalcolite cores or inclusions. Cristobalite - Cristobalite is present as thin clear coatings, and occurs in cavities and fills interstices between plagioclase plates in some of the coarser crystalline rocks. Microscopically it is characterized by a crackly surface and complex twinning. Troilite - Troilite occurs in small amounts as rounded masses in interstices between plagioclase, clinopyroxene, or ilmenite of some coarser crystalline rocks. Most masses contain small blebs of native iron. Native iron - Native diameter within the are also present. iron troilite occurs as scattered blebs up to I0 microns masses. Occasional isolated masses of iron Other minerals - Several other accessory rocks which include chromian ulvospinel, whitlockite, tranquillityite, zirconolite, For further New York, description and reference, (1975) 323 pp. minerals occur in crystalline ulvospinel, apatite, K-feldspar, and baddeleyite. see Frondel, J.W. Lunar Mineralogy. 37 Apollo II Sample Degradation History There are two basic areas of sample degradation to be considered in Apollo II: I) Sample contamination during collection and transportation of samples back to earth; and, 2) Laboratory contamination during original processing. Tools used on the lunar surface for sample collection (hanTner, tongs, etc.) were stored in two different configurations in the Modularized Equipment Storage Assembly (MESA). Core tubes, solar wind experiment, and teflon storage and collection bags, were cleaned to high standards (Apollo II, 12 & 13 Organic Contamination Monitoring History) MSC-04350 and vacuum sealed in the ALSRC containers at the Lunar Receiving Laboratory. All other large tools (scoops, tongs, etc.) were cleaned to spacecraft cleaning levels. These levels were reported as being equivalent to laboratory cleaning levels used on LRL tools (personal conversation with W.A. Parkan). However, all tools not sealed in the ALSRC were hand checked in a clean room environment, prior to loading into the MESA. At this time it is possible that the hand tools could have been handled by someone without gloves;. On the lunar surface, the astronauts probably handled a few of the larger samples without using any tools. EVA suits worn by Armstrong and Aldrin were cleaned only to a visual cleaning requirement. This meant that they were probably the "dirtiest" item to come in contact with any samples at that point in the mission. Spacesuit out-gassing may have been another minor contributor to surface contamination. Lunar surface contamination from exhaust emissions of the lunar module may have occurred during landing. Since all rocks and soils were collected in a small radius around the LEM, it is possible that residue from the descent engine contaminated certain surface samples. This possibility has been studied and documented, (Murphy et al., 1970). However, no direct conclusions were reached. In the LRL, cabinets in which lunar samples were to be processed were cleaned with alcohol and flushed with freon. This was repeated several times to ensure no biological contamination of the samples. During the quarantine period, containers or tools transferred into any cabinet system in the LRL were flushed with peracitic acid and were put through a dry heat sterilization process. The amount of heating was not any different from the daytime temoerattJrp_ nn fh: mnnn. No CAq_ were recorded of pera_itic acid leaking through a container onto a sample. 38 The samples came in contact with teflon, aluminum and stainless steel, and were exposed to indium (used for sealing containers) and molybdenum disulfide (used as a lubricant). In addition to this, samples processed in PCTL were exposed to open Mettler balances, and immersion oils used in petrographic work. Samples in SPL were sawed in open air. Many samples repackaged during re-examination had been packaged in Bel-Art products, (polyethylene and polystyrene) which were labeled gummed labels, and written on with ball point pens. These products, exposed to samples, could have added greatly to sample contamination. In the present SSPL, samples only come in contact teflon and aluminum. Xylan is used as a lubricant molybdenum disulfide. During this re-examination, samples was noted in the data packs. were re-packaged with stainless in the place with if steel, of and old packaging All tools which touch samples, are cleaned to a CP-7* level. Most containers which samples are stored in, are also cleaned to a CP-7* level. All processing cabinets used for lunar samples, are cleaned to a CP-I* level. SAMPLE RE-EXAMINATION BINOCULAR DESCRIPTION PROCEDURE remaining subsample was selected for the descripSpecial emphasis was placed on the mineralic and rock. In general, the largest tion of the lithology. clast components of the Breccia clasts were measured, classified and described (see Table 4) and abundances of the various clast types were visually estimated. The identification, abundances and grain sizes of the basalt components were coordinated with the thin section descriptions. The orientations used in the photographs and in the binocular descriptions are arbitrary and do not reflect the orientation on the moon. *Contamination Control Procedures (MSC-03243) 39 For the most part, information contained in the binocular descriptions was generated during re-examination. However, sample descriptions generated during PET were reviewed and any information that conflicted with, or could not be observed during re-examination was annotated by placing a semi-colon (;) between the re-examined descriptive and the PET descriptive_ For example: If the part of the rock restudied had no fractures, Duz a note in the Preliminary Examination stated that fractures were present parallel to an elongated face, it would be presented in the following manner in the binocular descriptions: Fracturing All terms - Absent; the Few fractures binocular TERM parallel to elongated are listed face (PET). used in descriptions below: CHARACTERISTIC Cavities DEFINITION ANDCOMMENT Not to include merely surface related features such as clast molds. vugs vesicles crystals Coherence Intergranular: very friable coherent tough Fracturing: absent few numerous non-penetrative penetrative Component mafic silicate friable projecting or lining materials grain-to-grain crumbles under crumbles under coherence manual pressure manual pressure grains than a full must be struck breaks around across them to disaggregate grains rather terms combined description as needed for visible on opposing sides and fines as igneous rocks, applicable breccia all colored translucent minerals; mainly pyroxene and olivines light grey and white (if shocked) plagioclase 4O CHARACTERISTIC TERM ilmenite opaque black DEFINITION ANDCOMMENT opaque submetallic used when opaques other than ilmenite are present but quantitatively inseparable amber to honey brown to dark brown aphanitic material microscope) <0.05 mm; sometimes mesostasis (under referred binocular to as of pyroxene mafic clast glass Fabric isotropic anisotropic laminated equigranular inequigranular porphyritic seri ate microbreccia fine breccia see clast descriptions for various clast lithologies dark green to black silicate material to include texture details noncrystalline 5mm average clast clast clast size size size breccia Surface specific faces may be referenced by the laboratory orientation cube face designation irregular granulated smooth hackly glass grooved covered(%) generally e.g., for glass a freshly 30% of broken surface E and 10% of T surfaces slickenside-like Variability* any difference from one part size, lithology, in any characteristic to another, e.g.,grain mineralogy *The variability term homogeneous, when used in reference to breccias, refers to no major variation between distribution and abundance of clast material or major components. 41 CHARACTERISTIC Zap Pit TERM none few many DEFINITION ANDCOMMENT none seen in quick scan lO/cm 2 42 43 A C) 0 _._ _°_0_ ,?

The modal analyses are based on 200-400 point counts, the number depending on the apparent heterogeneity of the sample. The modal analyses reported always represent void-free analyses owing to the variability in the number, size, and distribution of voids. For the size characterization used. Identification of No attempts were made to composition present. No was made to identify any the maximum dimension of each crystal was the phases was solely by optical properties. identify the specific pyroxene or plagioclase oil immersion microscopy was done and no attempt of the very fine grained materials. BRECCIA IN THIN SECTION GENERAL DESCRIPTION OF AN APOLLO II Since the overall characteristics of all the Apollo II breccias are very similar, a generalized description and definition of terms is given below. For specific samples, only those characteristics that deviate from the general description will be noted. Apollo II breccias are characterized by having a dark to light brown matrix which is rich in slightly to moderately devitrified glass. In most cases the material is very turbid and contains small crystallites, many too small to be resolved. The following definitions will be used in describing all breccia samples: Matrix - The matrix of the section is that material in which the glass-rich phases occurs along with small (Imm) and each has a few remarks to better define the clast components and any other pertinent information. The exact number of the large clasts is given, 49 whereas only a relative abundance is given for the small clasts. Due to the heterogeneous nature of breccias, one or even several thin sections cannot give precise percentages of phases present. Therefore, in order not to stress unduly the measured values of the phases present in the sections, semi-quantitative values are used. These values are defined below: Relative Value Approximate % of Type Present >50% 30-50% 20-30% 10-20% <10% in Section Very abundant Abundant Moderate Few Present In the majori_' of the breccias, the matrix forms a more or less continuous array and hosts all other phases present. The matrix is a semiopaque glassrich phase that: shows no flow structure but always shows some degree of devitrification. Included in the matrix are numerous rounded and irregular lithic clasts. These clasts are randomly located and isolated from one another. Many breccias have a wide variety of clasts while others have a very limited representation. Interdispersed with the lithic clasts are mineral clasts. The major phase represented is usually clinopyroxene. It occurs as irregular to blocky shards which usually show some degree of shock deformation. The crystals, for the most part, show only slight to no evidence of reaction with the enclosing matrix. Plagioclase and ilmenite also occur" in most sections, but usually to a lesser degree. The third major phase is the glass shards which occur as spherical to irregular masses. Many contain bubbles, flow lines and fractures. The color usually is some shade of yellow or orange, but colorless, white and greenish-brown masses also occur. Some glass coatings on vesicle walls and near the outer surfaces also occur.

No attempts were made to determine any of the phases in the mesostasis. SAMPLE HISTORIES A summary of the processing, laboratories and operation, special handling and any unusual contaminating conditions is presented for each generic sample. In addition, an abbreviated sequence of laboratory destinations is presented for each pristine subsample. This indicates which laboratory and hence type of potential contaminants could be associated with the existing sample. More detailed information may be found in the Curator's files.

Some smaller euhedral crystals are found within a few of the crystals of plagioclase. Some zoning is present, but it is not pronounced. Some small subhedral crystals exhibit clear cleavage traces, simple twinning, and appear to have formed at a different stage of crystallization from the majority of the clinopyroxene. Plagioclase - Small tabular crystals of plagioclase form distinct groupings, while the majority of the plagioclase, in the section, forms anhedral crystals in the interstercies formed by the pyroxene-ilmenite network. Twinning in the crystals is common and pronounced. Opaques - Two generations of ilmenite occur in the section. The first forms small lath-like to skeletal lath-like crystals. The second type forms large, blocky, anhedral crystals which have a sieve texture and many re-entrants which are filled by the two silicate minerals. Isolated masses of troilite and troilite with iron-nickel are found throughout the section. Some are associated near ilmenite crystals while others are isolated along the boundaries between the silicate phases. Occasional iron-nickel vein fillings are observed in the fractures within the silicates. Mesostasis - Isolated irregular masses of a glass-rich phase occupy boundar_ voids between adjacent silicate phases. The size of the masses are from 0.05 to O.Imm. The masses are very turbid and distinct crystals were not observed. B.M. French et al., (1970) have described I0017,16 in some detail. Their modal analysis was: Clinopyroxene, 49.7%; plagioclase, 18.0%; ilmenite, 23.9%; and, mesostasis, 8.3%; which is in good agreement with the above analysis. TEXTURE: The rock consists of a random network of intergrown clinopyroxene and ilmenite crystals. Plagioclase and glassy mesostasis occur interstitial to the pyroxene-ilmenite network. The overall texture is poikilitic. The plagioclase crystals display a moderate alignment suggesting flow within the crystallizing lava. Vesicles are rimmed by small clinopyroxene crystals. Sharp boundaries occur between all phases except the mesostasis. 102 10017 SELECTEDREFERENCES: Adler et al. (1970), Brown et al. (1970), Dence et al. (1970), French et al.

This network then hosts all other phases present. Many of the pyroxene crystals are polygranular, but appear as a monocrystal in plane light. Many of the vesicles are lined with very fractured pyroxene crystals. Many of the subhedral crystals of ilmenite are wholly enclosed in pyroxene crystals. Plagioclase - The plagioclase crystals in this rock differ somewhat from the typical Apollo II intersertal basalt. Nearly every crystal is anhedral and occurs as interstitial void fillings in the pyroxene-ilmenite network. In section, however, many of the crystals appear as acicular crystals sometimes with glass centers. No well defined crystal could be found. Isolated crystals are rare to absent. The twinning is poor and extinctions uneven. A few fan-shaped masses are present, but again are not composed of euhedral crystals_ Isolated terstitial Many of terface. patches of a glass-rich mesostasis also occur as an incomponent in the network. The color is a dark brown. the masses occur near or at a plagioclase-pyroxene inThe masses are turbid and very irregular in shape. Opaques - llmenite makes up, by far, the most abundant opaque mineral in the rock. Two generations of crystals are present in the rock. The first type forms larger skeletal crystals with several of the crystals having chromite and rutile exsolutions. These crystals are very erose and the embayments are predominately filled with pyroxene. The second type forms smaller lath-like crystals, some of which are quite thin. In section many of these appear as long thin acicular crystals. Several of these crystals are bent and broken. TEXTURE: Fine-grained intersertal basalt consisting of a network of pyroxene crystals that are intergrown with larger skeletal ilmenite crystals. Interstitial to this network are crystals of plagioclase and masses of mesostasis. Small subhedral to nearly euhedral crystals of ilmenite occur included in some of the pyroxene grains. The plagioclase is all or nearly all interstitial while appearing as long acicular crystals in the section. Contacts are sharp between all phases. Selected References: Smith, J.V. et al.

Well developed cleavage is found in many crystals, while fracturing is present in all the crystals. No marked zoning, but occasional twinning is present, The crystals make up an almost continuous array with many areas consisting of only polygranular pyroxene. All contacts with the other crystalline phases are sharp and the mesostasis present in the section usually occurs between adjacent pyroxene crystals. The mesostasis forms dark brown poorly defined irregular masses throughout the section. The boundaries between the crystalline phases and the mesostasis are ill defined and the glassy material appears to have filled interstitial openings in the other phases. Some devitrification has taken place as the masses are very turbid. Plagioclase - Two major types of plagioclase occur in the rock. The larger anhedral crystals are skeletal, poorly formed and form interstitial masses between the pyroxene crystals. The smaller acicular crystals are lath-like and may have hollow centers filled with a glassy phase. These crystals form intergrowths with acicular pyroxene crystals in more or less fanshaped manner. Many of the terminations are quite splintery. Small crystals of an apatite-like phase is present associated with the plagioclase. This phase was not identified. Opaques - The primary opaque phase present in the rock is It forms skeletal crystals which are scattered throughout section. Few terminations are present on any crystals. chromite exsolutions are present.

Many of the crystals have been granulated while retaining the monocrystalline appearance. These crystals form the host medium for all other phases present. The extinctions are, for the most part, poor with few grains giving sharp extinction points. Almost all crystals show a pronounced fracture pattern with minor cleavage parting developed. A few crystals show a well developed cleavage pattern. Small crystals of pyroxferroite are associated as overgrowths on the pyroxene crystals. These crystals form sharp contacts with the pyroxene. Many of the fractures in the pyroxene continue through the adjacent pyroxferroite overgrowth. The pyroxferroite masses are scattered throughout the section and no localized concentration was noted. Plagioclase - Two generations of plagioclase occur in first type are euhedral tablets which appear in the equant to acicular crystals. The crystals show well planes and extinctions are sharp. There appears to orientation to the crystals yet there is only minor the rock. The section as developed twin be a preferred clustering. The second type of crystals represented in the rock forms interstitial masses between the pyroxene-ilmenite-plagioclase network. The masses are larger than the euhedral crystals and show poorer twin planes and extinctions are patchy. This later formed plagioclase is most often associated with the mesostasis that occurs in the rock. The mesostasis is light brown in color and very turbid. Cristobalite - A relatively large amount of cristobalite occurs in this sectio!n. Chao et al. (1970) found 4.5% in another section of this rock. This section may, therefore, be atypical. The anhedral masses are all as interstitial fillings between other crystalline phases. Opaques - As is usual for Apollo II basalts, the most common opaque mineral present in the rock is ilmenite. The crystals form subhedral to skeletal masses scattered throughout the rock. The subhedral crystals are associated with plagioclase and cristobalite while the skeletal c_Istals form in the plagioclase-pyroxene network. Small masses of troilite and troilite with iron-nickel inclusions are also present. These form only a very small percentage of the opaque phases present. Most of the masses occur with or near the ilmenite crystals. 210 I0047 TEXTURE: Subophitic medium-grained basalt consisting of pyroxene, two generations of plagioclase, ilmenite, and cristobalite with minor other phases. Only moderate shock effects are evident in the section. Contacts are sharp and little to no interreaction between phases was noted. Selected References: (1970), Lovering Chao et al.

Most of the silicate crystals are poorly formed and optical characteristics are poor. A few euhedral pyroxene crystals are present, but are scattered. The ilmenite occurs in crystals of two generations. One generation is composed of small euhedral laths and the other as large subhedral laths with irregular boundaries. Many of the larger ilmenite crystals contain silicate or glassy inclusions and have a somewhat sieve texture. Throughout the section are masses and stringers of a glass-rich mesostasis.

Some euhedral crystals, hexagonal in outline, are scattered randomly in the section. They show poor optical characteristics, but do have sharper grain boundaries. The larger subhedral crystals show some zoning, and all the crystals are highly fractured. Most of the grain boundaries are poorly defined. Due to the poor optical characteristics of the pyroxene crystals, no exact determination of the type of pyroxene could be made. Plagioclase - Small tabular crystals of plagioclase occur interdispersed with blocky anhedral crystals forming interstitial fillings within the pyroxene-ilmenite network. The optical characteristics are, for the most part, poor. Some of the smaller tabular crystals have retained sharp twin planes. The plagioclase grain boundaries domly scattered grains tend to have sharper and more well than do the pyroxenes.

The smaller euhedral laths are widely scattered throughout the section while the larger subhedral laths are somewhat more grouped. The larger crystals contain glass and silicate inclusions and the boundaries are very irregular. Many of the crystals are bent and some are broken. Many of the crystals are surrounded by the glass-rich mesostasis. Much of the mesostasis is present as stringers or as isolated masses filling interstices in the silicate-ilmenite network.

The crystals show sharp to distinct extinctions with moderate zoning. Small euhedral to anhedral crystals of olivine are present in several crystals. Many of the c_stals are granulated while retaining the monocrystalline appearance. Almost all crystals show a pronounced fracture pattern with only a minor cleavage pattern developed, A few crystals show simple twins, but this is rare. Plagioclase - Two generations of plagioclase occur in the rock. The first type consists of euhedral tablets which appear in the section as equant to acicular crystals. The crystals show well developed twin planes, sharp extinctions,and minor clustering. The second type of crystals representedin the rock forms interstitial masses between the pyroxene-ilmenite-plagioclase network. The crystals are larger than the first type and show poor optical characteristics. A possible third generation may be present and is represented by very small, sharp, isolated euhedral crystals completely enclosed in the pyroxene. These crystals may belong to the first generation or may represent a completely independent generation. Associated with the second generation of plagioclase crystals are small irregular masses of glass-rich mesostasis. The color is light to dark brown. Some devitrification has taken place, but no phases were determined. Cristobalite- Randomly scattered throughoutthe section are anhedral crystals of cristobalite. The grains are found between adjacent pyroxene-plagioclase crystals or between two grains of pyroxene. The later case is the more common. Opaques - The most abundant opaque in the rock is ilmenite which occurs as subhedral to skeletal crystal masses scattered throughout the 2 2 3 10050 rock. The lath-like crystals tend to form near the crystals of plagioclase and cristobalite. The skeletal crystals are randomly scattered in the silicate network. Some rutile and chromite exsolutions are present.

Sharp contacts between all pyroxene crystals and the other phases Plagioclase - Small tabular crystals of plagioclase predominate as the interstitial mineral within the pyroxene-ilmenite network. Also included in the interstices are anhedral, blocky crystals of plagioclase. The tabular type show well developed twin planes while the blocky crystals show poor development or none at all, Many of the crystals have glass or silicate inclusions. The crystals are randomly scattered throughout the rock with no preferred orientation. Opaques - Two populations of ilmenite crystals occur in the rock. The first type are large lath-like crystals which grade to smaller subhedral somewhat skeletal crystals. Many of the crystals contain silicate inclusions. These two types tend to merge and grade from one type to the other. Associated with the ilmenite are small (O.O05-O.Olmm) masses of troilite with iron-nickel inclusions. Isolated larger masses of troilite (O.-l-O.09mm) without iron-nickel inclusions occur between the crystals of pyroxene. Mesostasis - Irregular patches of pale brown to clear glass rich mesostasis occur throughout the rock. The masses have a "bubbly" appearance and are made up of irregular patches of devitmified phases intermixed with the glassy phase. No identification of the phases present was made. The patches fill void areas between adjacent crystalline phases. The contacts with these phases are sharp and no reaction with the glass phase was noted. TEXTURE: Intersertal basalt consisting of a random network of subhedral pyroxene and ilmenite with interstitial anhedral plagioclase and mesostasis. Some graduation in the development of the ilmenite crystals is present. A similar graduation is also noted in the plagioclase development. The vesicles tend to be rimmed by small pyroxene aggregates. All contacts between phases are sharp. Selected References: Essene et al. (1970), Lovering et al. (1970), Reid et al. (1970), Haggerty et al.

The extinctions are, for the most part, poor with few grains giving sharp extinction points. Almost all crystals show a pronounced fracture pattern with minor cleavage/ parting developed. Some crystals have sharp, well defined cleavage patterns. Small crystals of pyroxferroite are associated as overgrowths on the pyroxene crystals. These crystals form sharp contacts with the pyroxene. Many of the fractures in the pyroxene continue through the adjacent pyroxferroite overgrowth. The pyroxferroite crystals are scattered throughout the section and no localized concentration was noted. Plagioclase - Two generations of plagioclase occur in the rock. The first generation consists of long tabular crystals and appears in the section either as well defined rectangular or acicular crystals. The second generation occurs as anhedral void fillings in the pyroxene-ilmenite-plagioclase network. The first generation crystals are clearly grouped into masses within the rock. Some areas contain no plagioclase while others have a heavy concentration. All the first generation crystal exhibit sharp twin planes and extinctions. The second generation crystals show much poorer optical characteristics. Isolated, yet closely related to the colorless to pale brown mesostasis. glass has taken place. Cristobalite stitial - Large anhedral crystals fillings in the voids within plagioclase masses, Some devitrification are areas of the of of cristobalite the silicate occur network. as inter- Opaques - The most common opaque mineral present in the rock is ilmenite. The crystals are subhedral to very skeletal and are scattered throughout the section. Many of the crystals have finger-like projections forming a very erose crystal. Associated with the ilmenite are small masses of troilite, troilite with iron-nickel and baddeleyite. The masses of troilite are more often isolated and not directly associated with the ilmenite. The troilite with iron-nickel and the baddeleyite are, however, found intergrown with the ilmenite. The size of the troilite and troilite with iron-nickel is from O.Ol-O.2mm while the baddeleyite forms a few small (O.05mm) masses. TEXTURE: Subophitic medium-grained basalt consisting of pyroxene, two 10058 257 generations of plagioclase, ilmenite and cristobalite with minor other phases. The presence of baddeleyite is unusual for Apollo II basalts. Contacts are sharp and little to no interreaction between phases is present. Selected References: Brown et al.

The pyroxene forms large anhedral crystals with lath-like to anhedral crystals of i]menite in a continuous network. Interstitial to these phases are subhedral to anhedral crystals of plagioclase with minor glass-rich mesostasiso Isolated within the network are anhedral crystals of olivine. % OF SECTION 45 33 4 16 2 SHAPE Anhedral Tabular anhedral to Blocky,nhedral a Lath-likeo anhedral t Irregular SIZE (MM) 0.01-0.8 0.08-0.8 0.001-0.3 0.05-I.0 O.OOl-O.l PHASE Pyrox Plag Oliv Opaq Meso 288 10062 COMMENTS: Pyroxene - Pinkish tan to light brown anhedral crystals of clinopyroxene together with the ilmenite crystals form an almost continuous array hosting the other phases present. The crystals of pyroxene show little cleavage pattern and almost no suggestion of crystal faces. Occasional feathery masses occur between plagioclase crystals. Most of the extinctions are irregular to patchy. Plagioclase - Small subhedral crystals of plagioclase occur in the section associated with larger anhedral masses of plagioclase. The anhedral crystals form interstitial void fillings in the pyroxene-ilmenite network. Many of the larger crystals are somewhat skeletal in development. The smaller crystals show sharp to moderate twin planes while the larger crystals show little to none. Olivine - Small to large blocky anhedral crystal masses of olivine are scattered throughout the section. All are fresh crystals with small pyroxene rims. Several of the crystals occur as small cores in some of the pyroxene crystals. Mesostasis - Small amounts of an almost colorless to slightly brownish glass-rich mesostasis phase occurs usually between the plagioclase crystals and the adjacent pyroxene crystals. No phases were determined and the amounts were small. Opaques - The opaque phases represented in the section are ilmenite and troilite-iron nickel. Carter, J.L. and MacGregor, I.D. (1970) have reported armalcolite and chromian ulvospinel from this rock. Neither of these phases were seen in this investigation. Two generations of ilmenite are present in the section. The crystals occur as small lath-like crystal sections and also as large somewhat skeletal anhedral crystals. Both types occur in nearly equal amounts. Some rutile and chromite exsolutions are present in the larger crystals. Small masses of troilite-iron nickel are present, but are rather sparse. A few masses of just troilite are also present. TEXTURE: Interlocking anhedral crystals of pyroxene intergrown with two generations of ilmenite and two generations of plagioclase crystals in an ophitic texture.

It occurred as isolated ilmenite crystals. No cleavage was seen and it Plagioclase - Two generations of plagioclase occur in the rock. The first t_pe consists of euhedral tablets which appear in the sections as equant acicular crystals. The crystals show well developed twin planes and extinctions are sharp. The second type of plagioclase crystals represented in the rock forms interstitial masses between the pyroxene-plagioclase-ilmenite network. The masses are larger than the euhedral crystals and show poor twin planes and extinctions are uneven. This later formed plagioclase is most often associated with the mesostasis that occurs in the rock. The mesostasis is light brown in color and very turbid.
