       red cells indicate issues that need to be resolved


SMR:   I think that the igenous rocks definitions from QAPF triangles should express the modal mineral
       constraints in words and reference the field in the triangle; otherwise the written definitions are not
       useful.




SMR    I don't think the definition of the igneous rock category concepts should consist of a petrographic
       criteria or a chemical (TAS) criteria. These are different concept spaces.



SMR:   distinction between defining and typical properties must be clear in the definitions.

SMR    grain size cut off for fine grained-- 20 micron, 32 micron, 100 micron. Doesn't matter too much-
       very rare and difficult to actually work quantitatively with grain size this small in consolidated rock!



SMR    is a dominant constituent 75 percent or 90 percent--both conventions are used. Again, data are
       very rarely truly quantitative, but I still think a number value is necessary to make clear what
       'monomineralic' or 'dominant' means
SMR    calclastic sediment-- included in percentages for carbonate sediment, or considered a 'clastic'
       constitutent
SMR    is it necessary to have a fine-grained igneous rock category that may include exotic or normal
       composition rocks as well as a normal fine-grained igneous category that only includes normal
       composition rocks?
SMR    add calcarous sedimentary rock and dolomitic sedimentary rock categories (figure A-20, SLTTs
       [2004]), or change limestone and dolostone to these more general categories. In the name of
       keeping number of categories down, I'd vote for using the more general terms.
SMR    sand, sandstone, mud, mudstone, and conglomerate have to be used in very general sense,
       corresponting to NADM SLTTs sandy rock, muddy rock, conglomeratic rock, or else the concept
       space would have big holes in it for poorly sorted materials that would just have to be called
       clastic rock or clastic sediment.
SMR   Discussion of use of conglomerate, sandstone, mudstone, clastic wackstone, diamictite (and
      corresponding sediment terms). Clastic wackstone has no corresponding sediment category.
      Conglomerate, sandstone, mudstone are used when the clastic nature of constituent particles can
      be determined, and rock has structure and fabric indicative of deposition by 'normal' sediment
      transport and depostion processes--traction, suspension, saltation in water or air, resulting in rock
      that has sedimentary structures like bedding lamination, cross-bed structures, sorting of grainsize
      fractions in individual depositional units. The categories also denote that the mud size fraction is
      composed of mud size clastic particles.

      Clastic wackestone denotes the presence of at least 10 or 15 pecent of fine-grained material of
      indeterminant genesis--with the implication that some or all of it is related to diagenetic alteration
      of lithic fragments (see Dickinson, ). Beyond the presence of this indeterminant fine-grained
      material, there is no implication for size of other clastic particles. This term typically finds use to
      categorize dark colored sandstone and mudstone that contains abundant 'unstable' volcanic rock
      fragments that rapidly lose their identity as individual particles during lithification and diagenesis.
      Clearly, this category could be subdivided based on the size distribution of discernible clastic
      particles, e.g. abundance of particles larger than sand size.

      Diamictite denotes the presence of a mud matrix that encloses sand or larger size clastic grains,
      implying deposition by some sort of mass flow/mixing process (rock avalanche, landslide, lahar,
      debris flow), mixing of material of different sizes by glacial processes (various genre of till), or
      mixing related to explosive processes (e.g. bolide impact). The term was invented to describe
      such rocks without denoting glacial genesis explicitly. The term diamictite carries no denotation of
      grain size distribution other that the presence of some mud fraction. Clearly, this category could
      be subdivided based on the size distribution of discernible clastic particles, e.g. abundance of
      particles larger than sand size.

      As such, these three groups of categories are based on different concept spaces, with only
      limited correlatability of individual categories between the spaces.
hopefully they're all resolved.



LB: I think the QAPF constraints constrain (!) the definition too much, which links back to
Percy's comments about general definitions creating a better chance of user 'buy in'. For
example, can the concept of a 'diorite' (insert any igneous rock term touched by QAPF) only
be defined with reference to QAPF space, or is it acceptable to say that a crystalline igneous-
looking rock with lots of plag and mafic minerals and very little quartz is a diorite? I would
(strongly) argue for the less-constrained definition. Although it is very widely published (and
accepted), QAPF is only one attempt to place some boundaries around some very old terms
(eg. diorite was first used in 1819). Therefore, I prefer the mineralogical definitions
(inadequate as some of them may be), with a statement that the definition includes the
QAPF fields. Hopefully what I've done with the definitions reflects that.

LB: I'm a little worried that with the revision the genetic terms that Boyan worked so hard to
excise are creeping back in. I've tried to stick with the descriptive terms where possible and
rely on Genetic Category for the sed/ign/met classification, but as soon as you begin
lumping into parent categories it always seems to come back to genesis. This is probably
going to be an issue for a long time (and I don't have an answer for it)
LB: Although they provide different ways to name your rock, the IUGS definitions in the
glossary of terms do not distinguish a rock type based on how you came up with the name.
I would like to see a general definition that "includes subtypes 'defined with QAPF' and
'defined with TAS' ". This way we have an overarching concept that includes the
subconcepts.
LB: Totally agree - if only the reference definitions weren't so fuzzy to begin with, we'd be
fine…

LB: not sure on this one - do you mean sed rox only or all materials? The coarse/fine
grained boundary is 2mm for igneous rocks, but for many (most?) people that's still
phaneritic in hand specimen. For sedimentary rocks my vote is for the sand/silt boundary
(32 microns). I've tried to solve this by being explicit in all the concept definitions.


LB: agree. I've attempted to expunge 'dominant' in favour of a number (usually 75).


LB: probably. We need the high-level term for 'I can't tell anything else', depends how
important 'normal' vs 'exotic' is. I've constructed the 'aphanite' concept to serve this
purpose, see what you think.


LB: done



LB: hopefully what I've done with these concepts addresses your concerns!
LB: agree, though I would argue to include this in a future version of the vocabulary.

                                     that's my lack of knowledge rather than any deficiency on their part

                         Neuendorf et   Need to be clear that coarse grain size refers to fragments
                         al. 2005       produced by brittle deformation process. I don't think cementation
                                        is a necessary property; its certainly not identifying. (what is a non-
                                        consolidated crushed rock along a fault called?) Gouge and breccia
                                        are distinguished by grain size, so there needs to be some grain
                                        size criteria, but I don't think consolidation is a necessary property
                                        of either one. 0.1 mm (100 micron) is grain size used in NADM
                                        SLTTm as lower boundary for visible grains, but the concept is
                                        probably equivalent to the fine-grain concept in BGS system, which
                                        they cut off at 32 micron. Operationally these can't really be
                                        measured in consolidated material, they're guidelines, so I'm not

carbonate sedimentary NADM SLTT         inclusion of limestone category (narrow definition) leaves gap in
rock                  sedimentary;      system of categories, with nothing between carbonate sedimentary
                      Hallsworth &      rock and limestone--dolomitic limestones and impure limestones
                      Knox 1999         have no containing category except carbonate sedimentary rock. I
                                        don't think limestone will be so much more abundant than the
                                        dolomitic or impure limestones that we can ignore the others.
                                        Hallsworth and Knox usage corresponds to SLTTs (2004) calcitic
                                        (or aragonitic) sedimentary rock, renamed to calcareous

                                        definition to reflect the hierarchy I think we're after (this is the

carbonate sedimentary Hallsworth &    Preservation of depositional texture is part of Hallsworth & Knox
rock                  Knox 1999;      definition. I think concept denotes that grain size has to do with
                      NADM SLTT       original carbonate sediment particle size (Folk, 1962, Dunham,
                      sedimentary     1962). Folk and Dunham both use 10% as cut off for micrite (Folk)
                                      or mudstone (Dunham), Hallsworth & Knox raised this to 25% for
                                      internal consistency in their system. We need to decide if we
                                      want to use 10% or 25% as the cutoff for a constituent to be
                                      considered dominant, and use same logic consistently in
                                      other 'mono-constituent' categories. Dunham, Folk, SLTTs all
                                      use 20 micron as cut off for 'mud', Hallsworth and Knox use 32
                                      mircon; since determination of such grain size distinctions (on the
                                      order or less than thickness of a thin section) is difficult at best, it
                                      doesn't matter much to me which we use! LB: I'd favour the higher
                                      number to be more inclusive (and also because I've grown up with
                                      the Wentworth scale...)

sediment               after NADM     We need to decided how we'll deal with calclastic sediment-
                       SLTT           clastic material derived from previously lithified and eroded
                       sedimentary    carbonate rocks. SLTTs proposal (followed in SMR proposed
                       rocks          definition) is to restrict carbonate sediment to intrabasinal origin --
                                      i.e. a sand composed of carbonate grains derived from limestone
                                      outcrops would not be considered carbonate sediment. LB: in the
                                      example you give, would you expect someone to use a carbonate
                                      classification, or would they go straight to the clastic classifications
                                      (sand, diamicton), and then describe the clasts? I would do the
                                      latter - would be good to see what others think.

fault-related material   Sibson, 1977;     fault rock is not defined in this vocabulary (see proposal below , so
                         Scholz, 1990;     use in a definition is not internally coherent. Some cataclasites are
                         Snoke and         foliated due to material layering produced by deformation,
                         Tullis, 1998;     analogous to layering in gneiss. These are commonly called
                         Barker, 1998      foliated cataclasite. NADM puts on separate branch from
                         Appendix II;      cataclasite to avoid geometric explosion of terms because of
                         NADM SLTTm,       compositional subdivisions. 'Random fabric' needs to be clearly
                         2004              enough defined to determine if foliated cataclasites are
                                           cataclasites; if not a foliated cataclasite would have to be
                                           categorized as cataclastic rock. Do we need all three cataclasite
                                           series terms in the vocabulary or could we reduce the concept
                                           count with a single 'cataclasite-series' category that includes
                                           protocataclasite, cataclasite, and ultracataclasite? LB: I like
                                           this idea - can add the others in later as subtypes of the parent if

sediment                 SLTTs, 2004;      clastic sedimentary material definition is better. Should read
                         Neuendorf et      'Sediment in which at least 50 percent [start from sed material def]
                         al., 2005         of the contained particles were derived from erosion, weathering, or
                                           mass-wasting of pre-existing rocks or minerals, and transported as
                                           separate particles to the place of deposition by mechanical agents
                                           such as water, wind, ice and gravity.' Of course, one might ask if a
                                           mineral can be eroded, weathered, or mass wasted to form a
                                           particle... (or is it a particle composed of a mineral that is
                                           weathered, eroded, mass wasted...) I think inclusion of 'mineral'
                                           here obfuscates things. What is weathered, eroded or mass-
                                           wasted is a pre-existing compound material, whatever we choose

clastic sedimentary    Fairbridge and why non-calcareous? What if the fragments are limestone? LB:
rock                   Bourgeois      because if it was calcareous you'd use the carbonate classfication
                       1978           instead (which makes this proscriptive, so I agree it's undesirable)
                                      What does terriginous mean here? Good question! (gone now)
                                      Pettijohn (1975, p. 164) diamictite defines criteria as poor sorting
                                      and matrix supported clasts. Hallsworth and Knox (1999) state that
                                      strict descriptive definition relates to range
                                      of particle size and not to relative abundance of any or all
                                      size classes and reference Fairbridge and Bourgeois, 1978. Does
                                      there need to be some criteria for what constitutes a wide-
                                      enough range of particle sizes???

                                       diorite/monzodiorite as dioritic rock, and gabbro/monzogabbro as
                                       gabbroic rock (QAPF fields 9& 10). We have quite a few of these
                                       rock types in eastern Oz, so I'm reluctant to lump them all as you
                                       proposed.

                       extrusive rock    need for a 'volcanic material' category - any comments? 'Volcanic'
                                         is a (genetic) term that we've avoided elsewhere (fine-grained
                                         igneous rock et al.). Also has the benefit of keeping the category

                                         definition - at best - of the concept space), rather than provide an
                                         acceptable definitive statement of what it is. I've gone back to
                                         Neuendorf, which seems to give a more affirmative statement, but
                                         I'm still not sure I'm completely satisfied yet.

mylonitic rock        IUGS SCMR          usage of fine-grained here is questionable; grain size of matrix is
                      2007               dependent on grain size of protolith. Precisely what does 'strongly
                      (http://www.bgs    foliated' mean? Interpretation of ductile shearing genesis of course
                      .ac.uk/SCMR/)      has to be based on some textural criteria, but I'll grant we can get
                                         away with not trying to specify those criteria. Brodie definition says
                                         well developed schistosity, but this is not consistent with character
                                         of mylonites under Brodie et al or NADM SLTTm definitions of
                                         schistosity, thus use well developed foliation. Restriction of mylonite
                                         to fault rock--"rock formed in a fault zone" is also too restrictive.
                                         Brodie et al also state "in the field it is often not possible to
                                         distinguish a foliated fault rock formed by brittle deformation
                                         (foliated cataclasite) from one formed by crystal plastic or grain
                                         boundary sliding processes, or a combination of different
                                         deformation mechanisms. Hence these are all defined in the field
                                         by the term mylonite." Mylonite concept in this vocabulary is
                                         restricted to rocks interpreted to be product of crystal plastic
                                         deformation. Use more general category of 'fault rock' if brittle or
                                         ductile deformation is indeterminant.
foliated metamorphic   Marshak &       mylonitic rock is NOT any foliated rock! Concept corresponds to
rock                   Mitra 1988      mylonite of Brodie et al 2007 IUGS SCMR. See discussion of
                                       mylonite. LB: we've split the cataclasite series into the next step
                                       down, and I think there are sufficient differences between proto-,
                                       ultra- and mylonite that they could probably survive in here for now.
                                       I've removed blastomylonite as a concept, though, but left it as part
                                       of the definition here so it's not completely excluded.

ultrabasic igneous rock LeMaitre et al. olivine ratio is defined in triangles with pyroxene and hornblende.
                        2002            LeMaitre et al is not clear on whether Olivine is 40% of rock (text,
                                        p28), or 40% of Ol-clinopyroxene-orthopyroxene-hornblende (Fig.
                                        2.9). LB: if we take the text at face value (although I think they do
                                        mean the modal ratio), then we get a more inclusive definition for
                                        our concept, which is what we want. Also, I can't actually find a
                                        reference that states 'less than 10 percent modal melilite', so I've
                                        removed it (which gets us out of another nasty restriction).

igneous rock            Neuendorf et     generally corresponds to 'not fine-grained' in terms of Gillespie and
                        al. 2005         Styles 1999 or LeMaitre et al2002, but their cut off of 32 microns is
                                         probably too low to correspond to 'cannot be seen with naked eye.
                                         100 micron is probably a more realistic cut off grain size, but
                                         quantitative measurement of such grain sizes is rarely if ever
                                         undertaken, so the point is academic. LB: like the idea of 'in the
                                         order of'; reworded to specifically excluded 'exotic' rocks

fine grained igneous    LeMaitre et al. why crystalline instead of igneous?? The concept I think we need is
rock                    2002            of a category that subsumes phonolite and tephritic phonolite. The
                                        'thought to be' has to do with the metadata on the categorization
                                        process-- Term doesn't actually appear in LeMaitre et al., concept
                                        corresponds to phonolitoid field (LeMaitre et al., p. 39, Fig. 2.19)
                                        without denoting the categorization process. LB: I've maintained
                                        the allowed convention of appending '-ic rock' to all the field
                                        classification terms in place of '-oid'. LeMaitre allows this where the
                                        latter is 'felt to be linguistically awkward' (p.39). In my humble
                                        opinion, they're all pretty awkward!

                                        ends up in long arguments in proximal tuffaceous deposits that are

                                       stick with petrographic or chemical definitions, but not both.




pyroclastic rock       NGMDB;          issue-- the proposed definition results in only one narrow
                       LeMaitre et al. category under they pyroclastic rock concept (which I propose
                       2002            to add to vocabulary). The SMR_Def concept is a generic tuff
                                       category desiged to split 'pyroclastic rock' space into
                                       pyroclastic breccia (>75% block and bomb) and 'generic tuff'.
                                       If we follow this pattern, we might want to add 'pyroclastic
                                       breccia' as well...., or remove tuff, and just leave it at
                                       pyroclastic material, tephra, and pyroclastic rock. Inclusion of
                                       ignimbrite in the vocabulary results in some inconsistency
                                       about fragmental igneous rocks.... LeMaitre classification is
                                       not set up to allow for hierarchical grouping

mylonitic rock   after          size criteria would only allow 10% porphyroclasts, so the very few
                 Neuendorf et   p'clasts criteria is redundant. In case of homogeneous dense rock
                 al. 2005;      with little if any parallel structure, have to provide criteria to
                 ?NADM          distinguish from ultracataclasite. Very fine grained criteria is not
                 metamorphic    necessary (Brodie et al: "An ultramylonite need not be ‘ultra’ fine

                 vocabulary




                 NGMDB          definition should identify the more general category into which this
                                fits, e.g. NADM CompoundMaterial.

are determinable, deformation is dominantly a result of
crystal plasticity without loss of material cohesion.

unspecified genesis? (What about multiples - sedimentary, igneous, tectonic
etc.?)

LithologyType     GeoSciML_Lbibby_proposed definition 10/25/07
bauxite           Collective term for lateritic aluminous ores; an off-white, grayish, brown,
                  yellow, or reddish-brown rock composed of a mixture of various
                  amorphous or crystalline hydrous aluminium oxides and aluminium
                  hydroxides, principally gibbsite, some boehmite and diaspore, along with
                  some free silica, silt, iron hydroxides and especially clay minerals.

blastomylonite    Mylonitic rock in which porphyroblasts have grown and strained grains
                  have annealed; grain growth is pronounced compared to tectonic
                  grainsize reduction.
broken rock       Rock with less than 30 percent tectonic fragments, or consisting of
                  greater than 30 percent fragments, but fragments are not rotated with
                  respect to each other.
cataclasite       Cohesive, random fabric fault rock that consists of greater than 10
                  percent fragments bounded by fractures, with matrix comprising 50-90
                  percent of rock mass; matrix is fine-grained material caused by tectonic
                  grainsize reduction.
chert             Hard, extremely dense or compact, dull to semivitreous, microcrystalline
                  or cryptocrystalline siliceous sedimentary rock, consisting dominantly of
                  interlocking crystals of quartz less than 30 µm in diameter; it may contain
                  amorphous silica (opal).
clay              Either a sediment with >67% clay-size or colloidal particles, ie. less than
                  0.004mm (Neuendorf et al. 2005; particle size from Wentworth grade
                  scale), or an unconsolidated material composed of >25% clay minerals
                  (Pettijohn 1957), or a loose, earthy, extremely fine-grained, natural
                  sediment composed primarily of clay-size or colloidal particles and
                  characterized by high plasticity and by a considerable content of clay
                  minerals (Bates and Jackson 1987, def. B).
diorite           Phaneritic crystalline rock consisting of intermediate plagioclase,
                  commonly with hornblende and often with biotite or augite; colour index M
                  greater than 10, sodic plagioclase (An0-An50). Defined modally in QAPF
                  field 10.
foidolite         Phaneritic crystalline rock containing more than 60 percent feldspathoids
                  in total light-coloured constituents. Defined modally in QAPF field 15

framestone        Carbonate reef rock consisting of a rigid framework of colonies, shells or
                  skeletons, with internal cavities filled with fine sediment; usually created
                  through the activities of colonial organisms.
gabbro            Phaneritic crystalline rock composed essentially of calcic plagioclase,
                  pyroxene and iron oxides. Defined modally in QAPF Field 10.

kimberlite        An ultramafic rock consisting of major amounts of serpentinised olivine
                  with variable amounts of phlogopite, orthopyroxene, clinopyroxene,
                  carbonate and chromite; characteristic accessory minerals are pyrope
                  garnet, monticellite, rutile and perovskite. (LeMaitre et al. 2002, p. 97).

lamprophyre       General term for a group of rocks strongly porphyritic in mafic minerals,
                  typically biotite, amphiboles and pyroxenes, with any feldspars being
                  confined to the groundmass.
monzodiorite      Phaneritic crystalline rock intermediate in composition between
                  monzonite and diorite. Defined modally QAPF field 9.
monzonite          Phaneritic crystalline rock containing almost equal amounts of plagioclase
                   and alkali feldspar with minor amphibole and/or pyroxene. Defined
                   modally in QAPF Field 8.
mylonite           Strongly foliated fine-grained rock formed by ductile shearing; typically
                   has anastomosing foliation, S-C fabrics, ribbons, rounded porphyroclasts,
                   stretching lineation; 50-90 percent of rock is fine-grained matrix caused
                   by tectonic grainsize reduction.
phyllonite         Mylonite or ultramylonite composed largely of fine-grained mica that
                   imparts a sheen to foliation surfaces; macroscopically resembles phyllite,
                   but formed by mechanical degradation of initially coarser rock.

protocataclasite   Cohesive, random fabric fault rock with matrix comprising 10-50 percent
                   of rock mass; the presence of foliation or penetrative throughgoing
                   fractures that separate fragments preclude classification with this
                   concept.
protomylonite      Foliated phaneritic rock with 10-50% fine-grained matrix; contains
                   characteristic lenticular, megascopic particles that faintly retain primary
                   structures; much of the original rock texture and mineralogy remain intact.

skarn              remove?
 syenite           Coarse grained crystalline rock consisting mainly of alkali feldspar with
                   subordinate sodic plagioclase, biotite, pyroxene, amphibole and
                   occasional fayalite; minor quartz or nepheline may be present. Defined
                   modally in QAPF Field 7.
ultracataclasite   Cohesive, random fabric fault rock that consists of consists of greater
                   than 10 percent fragments bounded by fractures, with a matrix of broken
                   mineral grains comprising greater than 90 percent of the rock mass;
                   matrix is related to cataclastic processes.
ultramylonite      Very fine grained foliated rock with average grain size less than 0.032
                   millimeter, greater than 90 percent matrix and very few porphyroclasts;
                   may also be so deformed that primary structures and porphyroclasts are
                   obliterated, so that the rock is homogeneous and dense, with little if any
                   parallel structure.

SMR comments
use 'Residual material' category. Concept deemed too specific compared to
abundance of material and geologic significance relative to other categories.




Can't compose definition to distinguish from gneiss/schist/mylonite.


categorize based on kind of rock that is broken.


merge cataclasite, ultracataclasite and protocataclasite to 'cohesive cataclastic
rock' to avoid hairsplitting between categories that have similar geologic
significance and context.

use 'non-clastic siliceous sedimentary rock' if origin is not biogenic or unknown,
and 'biogenic silica sedimentary rock' if is biogenic (radiolarian, diatom, spicule…)


occurrence deemed too rare, unusual, and difficult to interpret, so can leave out.
Classify as mud, residual deposit, gouge if origin known, 'composite genesis
material' if not.




leave out specific low-quartz coarse-grained igneous rock types (syenite,
monzonite, monzodiorite, monzogabbro, diorite, gabbro)


don't use fine-grained/coarse grained distinction for these rare rocks--merge
foidite and foidolite categories.

merge boundstone and framestone from Hallsworth and Knox, tricky distinction,
and significance or abundance doesn't justify

leave out specific low-quartz coarse-grained igneous rock types (syenite,
monzonite, monzodiorite, monzogabbro, diorite, gabbro)

merge kimberlite, lamproite, lamprophyre into exotic mafite category; rare rocks
with generally very small outcrop area.
