  We also welcome (in their absence) Mr Ockert Oosthuizen & family – they joined at the Brooklyn Show in April, but
  unfortunately we lost their form and can’t send them this welcome (or any communication). If anybody knows this Rockhound-
  family living in the East of Pretoria, please contact Esté Steyn on 082 821 2018.

  WELCOME!! May your association with the Club be enjoyable, long and productive.



  Dear Members,
  I’m still in desperate need of help with the Newsletter, as my job involves much traveling lately and I’m not always in
  town when this important piece of communication needs to happen. If you are Microsoft Word literate (especially
  columns, tables, sections) and can assist, please contact me a.s.a.p.

2.   Mineral Meeting, May 2 (Report by Horst Windisch)
     It was a real treat to see 22 members and one guest
     turn up for the talk given by Maggie Loubser, from the
     Geology Department of the University of Pretoria. .
     The presentation was entitled “X-Ray Fluorescence
     and its uses in our daily lives”. Here we were
     introduced into the methodology of this process and
     how it can be used in our every-day lives, in addition to
     geology and mineralogy. In industries like the cement,
     plastic, paint, gold and copper industries make
     extensive use of XRF,. Also South African Airway are
     able to establish when certain moving parts in an aero
     engine show signs of wear, by analysing the
     lubricating oil by means of XRF All in all a very
     informative evening                                                                    Check out the ice on the van on Sunday

     Ten members attended this meeting where the subject                   Thank you Natalie.
     under discussion was ”Inclusions in Minerals”. Wiebke                 We WILL have you
     first gave an outline on how these inclusions came to                 back next year to tell
     be inside the minerals, but also mentioned the fact that              the rest of the story
                                                                           when you come back
     very little research had been published on this topic.
                                                                           AGAIN.
     Thereafter, a range of minerals were passed around
     the table and discussed including a lot of inclusions in
     quartz - inter alia, liquid bubbles, pyrite, fluorite,
     hematite, rutile, tourmaline, ajoite, papagoite and
     some other “unknowns”. Horst brought along a
     specimen of fluorite, but the supposedly oil inclusions
     could not be found.
5.   Monthly Outing to Bloemhof
     13 people went on this outing lead by Guido de Beer
     (Wits). Guido took the group to new agate sites, not
     previously visited.
     Guido commented:        “the outing was a cold but great
     success, and the participants were all very happy with their
     "new" agates, and the fact that they had a first choice on a
