Recent O-isotopic analysis of a probable paired stone...by the Open University resolves the material clearly within the winonaite field. Hello List, Does anyone have a NWA 725 thin section and a winonaite thin section? Maybe they could share their observations and conclusions with the List! Just a few hours ago we were discussing the problems that may arise when trying to "pair" meteorites, especially NWA's (from multiple sources). The "infamous" NWA 869-ers I own and that I have seen look so different I can hardly believe all of them are NWA 869. So, maybe Stan's paired stone and the *original* Tissemoumine (NWA 725) are not the same material?!?
