Northwest Africa 3149 Morocco Purchased August 2004 Achondrite (howardite) A very fresh 2594 g stone with complete black and brown fusion crust was purchased in Ouarzazate from a Moroccan dealer by A. and G. Hupé (xHupé) in 2004 August. Classification and mineralogy (A. Irving and S. Kuehner, UWS): Breccia consisting mainly of coarse grained mineral clasts with subordinate clasts of basaltic eucrite. Mineral clasts include abundant large, pale green diogenitic orthopyroxene (Fs25.3Wo2.0, FeO/MnO = 31.1), calcic plagioclase, exsolved pigeonite, silica polymorph, minor olivine (Fa44.4, FeO/MnO = 52.9), troilite, ilmenite (one with a baddeleyite inclusion) and metal (5% Ni). Several clasts consist of subhedral orthopyroxene grains within a matrix of troilite and partly altered metal. Specimens: type specimen, 20 g, and one polished thin section, UWS; main mass, xHupé. | ||||||||||||||||
