Northwest Africa 11241 (NWA 11241)

(Northwest Africa)

Purchased: 2016 Nov

Classification: Carbonaceous chondrite (CV3)

History: Two identical stones were purchased by Gary Fujihara in November 2016 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Granular chondrules (some relatively coarse grained, apparent diameter 600±300 μm) plus fine-grained elongate amoeboid CAIs (to 1.7 mm in the thin section, to 3 mm in the slices, but most are smaller) are set in a fine grained matrix (medium brown in thin section).

Geochemistry: Olivine (Fa0.4-39.2, N = 3), orthopyroxene (Fs0.7-1.0Wo1.1-0.9, N = 2), diopside (Fs1.3Wo45.1; Fs 0.5Wo49.3; Fs9.5Wo50.8; N = 3).

Classification: Carbonaceous chondrite (CV3). CAIs are unusually small for a CV3.

Specimens: 20.28 g including one polished thin section at UWB; remainder with Mr. G. Fujihara.
