Note that, in contrast to the Met Bull on line, in the new edition of "Meteorites from A to Z", the LL petrological types as given by Jeff are correctly mantioned, except for Bishunpur, which remained LL3.1 (but LL1.15 in Met. Bull.). Alex, 2 little sisters of your Krymka, a complete slice of 17.4 grams and another of 28.2 g will be exhibited next week-end in Ensisheim (theme: meteorites from Russia and Eastern Europe). More news on Ensisheim (latest info) to follow later today. Best to all, Zelimir A 17:34 16/06/2008 +0200, Alexander Seidel a ?crit : >Thank you, Jeff, for your quick reply.
