Purchased: 2016 Oct

Classification: Carbonaceous chondrite (CV3)

History: Purchased by Dustin Dickens in October 2016 from a dealer in Laayoune, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Ellipsoid-shaped granular chondrules (apparent diameter 900±600 μm) and irregularly shaped, fine-grained CAI are set in a fine-grained matrix (~35 vol.%, sepia brown in thin section) containing rare Zr-Pt-bearing nuggets. The long axes of chondrules show preferred orientation.

Geochemistry: Olivine (Fa0.2-61.8, N = 3), orthopyroxene (Fs0.9-1.3Wo1.1-1.2, N = 3), clinopyroxene (Fs0.6Wo34.6; Fs1.1Wo37.4; N = 2).

Classification: Carbonaceous chondrite (CV3).

Specimens: 32.2 g including one polished thin section at UWB; remainder with Mr. D. Dickens.
