Hi First You can make few thin section for lab or choose most representative 1x1" slice for one thin section. Second for example "NWA869 family" dont have soo many huge breccias for make from them thin section. Ofcourse if You want cheated classifiction, You will find clean L4 part and this one You can send to lab. For some reasons this will be cheat, for others not, becouse THIS L4 fragment is part of whole meteorite. But this will be not representative material. I think that for brecciated meteorites must be submited more than 1 thin section to minimize possibility of wrong classification. -----[ MARCIN CIMALA ]-----[ I.M.C.A.#3667 ]----- http://www.Meteoryt.net [EMAIL PROTECTED] http://www.PolandMET.com [EMAIL PROTECTED] http://www.Gao-Guenie.com GSM +48(607)535 195 --------[ Member of Polish Meteoritical Society ]-------- ______________________________________________ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
