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 27 at 113.61kg and not 26 at 110 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 27 at 114 kg, more specifically 12 at 113.636 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. (?)
