Hmm-ing again :-) "The winonaites are texturally similar to acapulcoites, but the winonaites contain coarser grains and abundant crosscutting metal-sulfide veins."
Could this by a typo because: Marvin's pic of the Acapulco thin section shows grains that are coarser than the ones of NWA 1054 ... and because: The Antarctic acapulcoite TIL 99002 is mineralogically similar to GRA 98028 but has a larger grain size (300-400 µm) than GRA 98028 (50-100 µm). (Met.Bull. 86, MAPS 37-7, July 2002). .. and now back to Hutchison who states in Table 8.2 on page 252: Grain-size of acapulcoites => 150-230 µm Grain-size of winonaites => 55-230 µm Regards, Bernd ______________________________________________ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
