Northwest Africa 8216 (NWA 8216)

(Northwest Africa)

Purchased: 2013 Dec

Classification: Primitive achondrite (Lodranite)

History: Purchased in Temara, Morocco by Adam Aaronson in December 2013.

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed of closely-packed angular mineral grains within sparse matrix, and characterized by large, green clinopyroxene grains and staining around some metal grains. Minerals are olivine, orthopyroxene, clinopyroxene, chromite, troilite and stained kamacite.

Geochemistry: Olivine (Fa11.4-11.5; FeO/MnO = 23-25), orthopyroxene (Fs10.1-10.2Wo3.1-3.8; FeO/MnO = 14-15), clinopyroxene (Fs4.5-4.6Wo43.0-43.3; FeO/MnO = 9-10).

Classification: Lodranite breccia. This material is likely paired with NWA 8118 and NWA 8251.

Specimens: 20.3 g including a polished thin section at UWB. The remainder is held by Aaronson.
