Hello Zelimir, Norbert and all, In a very recent conversation Tony Irving told me that he was re-doing the classification of Tafassasset with Ted Bunch, and that the results would be published in a formal paper. I belive they are practically done so the new classification should be announced pretty soon. And it is not bracchinite or CR6, and it is very interesting, but I would prefer to let them tell the story themselves.
More soon. Anne M. Black _http://www.impactika.com/_ (http://www.impactika.com/) [EMAIL PROTECTED] (mailto:[EMAIL PROTECTED]) Vice-President, I.M.C.A. Inc. _http://www.imca.cc/_ (http://www.imca.cc/) In a message dated 11/26/2008 9:52:23 AM Mountain Standard Time, [EMAIL PROTECTED] writes: Hi Norbert, Bernd, Harald, List, Thank you very much for the info about "Grein 004/Tenere 001/Tafa". I indeed read that somewhere sometimes but I have not my archives on hand here in France (BM Met. Catalog (Grady) indeed currently gives most of the meteorite synonyms). Bernd said: "Grein 004" as well as "Tenere 001" are just synonyms for the Tafassasset Freiburg mass, a single stone weighing 3610 grams. It's no pairing. Bernd, Norbert, does that mean that the tkw for Tafassasset is then 110 kg (Franch find) + 3.61 kg ("Grein 004") = 113.61 kg ? (thus [EMAIL PROTECTED] and not [EMAIL PROTECTED] kg as in "A to Z" ?). Met. Bull. indeed reports the tkw as 114 kg (approx), which well fits the figure. The official type so far is CR-an (Met. Bull.), or PAUNGR ("A to Z"). Do you agree ? I know that both meteorites were studied separately and that the real type could not be defined. Note that Weir (his web site) reports, for T-1 (= Tenere 001), a total weight of exactly 3.636 kg, also that is "brachinite-related" and that Tafa itself (separately listed by Weir but said being paired with T-1) is a "PAUNGR, possibly CR-related". More recent studies seem to still question that CR-relation... I understand the real type is yet to be defined and that the tkw is close to [EMAIL PROTECTED] kg, more specifically [EMAIL PROTECTED] kg Norbert, do you think Prof Otto knows more on that or whether they continue to study this meteorite in Freiburg ? And Bernd, what you mean by "it's no pairing" ? Everybody seems to agree so far that the "Freiburg mass" is also Tafa. (?)
