And no doubt, Rose City is a smashing meteorite (heh-heh) having been studied by a "Who's Who" of great meteoriticists. Looks like whole stone analysis was performed by Brian Mason, D. Stoffler on shock metamorphism, D.D Bogard himself on impact age, and our own Alan Rubin checking the breccia. Did I mention that old Harvey himself (Nininger) mentioned it in a letter of 11 November, 1933? Anyone selling this? FYI - 80% of the Rose City 10.5kg fall (total of three individuals) is in Chicago (possible trade for Park City?), Washington (the Smith), and NYC (AMNH). Thanks also to Sir Eric and Madam Anne for their noting of a pending Gao-paired possibility. G'Day to Jeff down under for flagging a couple slick Saharans. A cappuccino to Matteo for picking up on DAG 880 in a future MetBull. A buttery croissant to Vincent Jacques for posting photos of an interesting met named Rammya (Moroc/1996). Bernd gets a beer for adding: SAU 033, DaG 172, QUE 99396 (maybe), and Yamato 790746. But highest kudos to Matt Morgan for digging up "Spade" H6 , an "annealed" impact melt not yet listed in the Cat of Mets. Get jiggy with it and read Alan Rubin's LPS 2003 article Matt pasted to his post. But before you click, have a little tease - "shock induced damage of the olivine crystal lattice can be annealed out.......thus making a chondrite appear less shocked than it was at an earlier point in history." So a stage "S3" could be, maybe, it is.... shocked BACK to an "S1". I'll pass this update on to Blaine. With all these "H" impact melt breccias around, I want a discount!
