(Northwest Africa)

Purchased: 2014 Sep

Classification: Primitive achondrite (Lodranite)

History: Purchased by Stefan Ralew in September 2014 from a dealer in Zagora, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Matrix-poor breccia composed mainly of coarse mineral grains (up to 5.5 mm) of olivine, orthopyroxene, clinopyroxene, chromite, kamacite (altered to iron hydroxides) and troilite. Olivine contains numerous tiny inclusions composed of chromite+clinopyroxene.

Geochemistry: Olivine (Fa10.4-10.9, FeO/MnO = 21-23, N = 3), orthopyroxene (Fs9.1-9.4Wo1.1-3.2, FeO/MnO = 14-15, N = 2), clinopyroxene (Fs3.5-3.7Wo44.7-45.5, FeO/MnO = 7-10, N = 2).

Classification: Lodranite. Paired with NWA 10145.
