Writeup from MB 104:

Northwest Africa 10152 (NWA 10152)

(Northwest Africa)

Purchased: 2014 Jul

Classification: HED achondrite (Diogenite, polymict)

History: Purchased by Stefan Ralew in July 2014 from a dealer in Foum el Hisn, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of angular mineral clasts of mainly diogenitic orthopyroxene with minor calcic plagioclase, olivine, chromite, exsolved pigeonite, troilite and Ni-free metal in a finer grained matrix. The eucritic exsolved pigeonite and calcic plagioclase make up less than 10 vol%.

Geochemistry: Olivine (Fa22.8-23.0, FeO/MnO = 48-57, N = 2), orthopyroxene (Fs21.4-21.9Wo2.3-3.6, FeO/MnO = 26-28, N = 3).

Classification: Diogenite (polymict breccia, olivine-bearing).

Specimens: 20.0 g including one polished thin section at UWB. The remainder is held by Ralew.
