Northwest Africa 11320 (NWA 11320)

(Northwest Africa)

Purchased: 2017 Feb

Classification: Carbonaceous chondrite (CV3)

History: Purchased in Morocco by Habib Naji in February 2017.

Petrography: (A. Irving and S. Kuehner, UWS) Ellipsoidal chondrules (mostly granular, but some BO and PO types; apparent diameter 800±500 μm, N = 12) and relatively abundant, elongate, irregularly shaped, fine-grained CAI occur in a relatively sparse matrix (~35 vol.%, orange in thin section). Chondrules and CAI exhibit some preferred orientation of their long axes.

Geochemistry: Olivine (Fa0.1-42.6, N = 3), orthopyroxene (Fs0.8-0.9Wo0.9-1.1, N = 2), clinopyroxene (Fs0.3Wo34.0; Fs0.7Wo41.6; N = 2), clinopyroxene in CAI (Fs49.6Wo49.4).

Classification: Carbonaceous chondrite (CV3).

Specimens: 21.79 g including one polished thin section at UWB; remainder with H. Naji.
