Writeup from MB 106:

Northwest Africa 10368 (NWA 10368)

(Northwest Africa)

Purchased: 2015 May

Classification: Primitive achondrite (Lodranite)

History: Purchased by Fabien Kuntz in May 2015 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Coarse grained fragmental breccia composed of clasts (up to 3.8 mm) of single mineral phases plus some composite clasts in a sparse matrix. Major minerals are olivine, clinopyroxene and orthopyroxene with accessory Cr-rich chromite, altered kamacite and pyrrhotite. Olivine contains relatively abundant round blebs composed of kamacite + pentlandite. Grain boundaries are stained by secondary iron hydroxides.

Geochemistry: Olivine (Fa10.6-10.7, FeO/MnO = 22-23, N = 3), clinopyroxene (Fs3.7-3.9Wo45.3-45.2, FeO/MnO = 9-10, N = 2), orthopyroxene (Fs9.7-9.8Wo1.2-2.5, FeO/MnO = 14-16, N = 2).

Classification: Lodranite breccia.

Specimens: 20.43 g including one polished thin section at PSF; main mass with Kuntz.
