Hi Mendy and List, You inquired:
"Can someone please clarify why this is listed as a Brachinite instead of diogenite? Based on the composition being 90% olivine, should this not be listed as a dunitic diogenite?" Because igneous-textured brachinites are olivine-rich rocks (79-93 vol% olivine) too. Looking forward to my little slice from Fabien and also looking forward to looking at it under the microscope. Maybe the size of the crystals can shed a bit more light on this "enigmatic puzzle"! But, whatever it is, it is an achondrite and it is beautiful, ... and thin sections may also be helpful in "solving" the riddle! Best wishes, Bernd ______________________________________________ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
