Northwest Africa 3135

Morocco

Purchased 2003 September

Achondrite (ureilite)

A 45.8 g greenish-grey stone, almost completely coated with a fresh, black, semi-glossy fusion crust, was purchased at the Denver Gem and Mineral Show by A. and G. Hupé (xHupé) in 2003 September.  Classification and mineralogy (A. Irving and S. Kuehner, UWS):  Aggregate of olivine (Fa23.2, CaO = 0.25 wt.%, MnO = 0.40 wt.%) with subordinate orthopyroxene (Fs18.7Wo4.3, Cr2O3 = 1.05 wt.%, FeO/MnO = 31.4), some exsolved pigeonite and about 10% fine grained, dark intergranular material (containing partly altered Ni-poor metal, troilite and presumably carbon phases).  The difficulties in cutting and polishing this sample suggest the presence of microdiamond.  Olivine grains adjacent to matrix have reduced rims (as Mg-rich as Fa8.1) containing fine metal blebs, and FeO and MnO contents of olivine cores in fall on the correlation line established for ureilites (see Mittlefehldt et al., 1998, Fig. 34).  Specimens: type specimen, 9.12 g, and one polished thin section, UWS; main mass, xHupé.
