Writeup from MB 104:
Northwest Africa 10181 (NWA 10181) (Northwest Africa) Purchased: 2015 Feb Classification: HED achondrite (Diogenite, polymict) History: Purchased by GHupé in January 2015 from a Moroccan dealer at the Tucson Gem and Mineral Show. Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed of predominantly diogenitic orthopyroxene clasts (~95 vol.% of clast population), autolithic breccia clasts, sparse basaltic eucrite clasts, plus related mineral debris set within a sparse matrix (constituting ~5 vol.% of the specimen). Other minerals are exsolved pigeonite, calcic plagioclase, pigeonite, olivine, silica polymorph, Al-Ti-chromite, stained kamacite, taenite and troilite. Geochemistry: Olivine (Fa34.9-36.8, FeO/MnO = 47-53, N = 2), diogenitic orthopyroxene (Fs23.0-23.1Wo1.8-2..6, FeO/MnO = 30-33, N = 3), orthopyroxene host (Fs61.7Wo2.4, FeO/MnO = 33), clinopyroxene exsolution lamella (Fs29.1Wo42.0, FeO/MnO = 36), pigeonite (Fs46.7Wo5.2, FeO/MnO = 22). Classification: Diogenite (polymict breccia). Eucrite material makes about 5 vol% of the meteorite. Specimens: 35 g including one polished thin section at UWB. The remainder is held by GHupé. | ||||||||||||||||||||||||||||||
