Writeup from MB 104:

Northwest Africa 10200 (NWA 10200)

(Northwest Africa)

Purchased: 2014 Sep

Classification: Ordinary chondrite (L3)

History: Purchased by John Curchin in September 2014 from a Moroccan dealer at the Denver Show.

Petrography: (A. Irving and S. Kuehner, UWS) Highly unequilibrated specimen composed of closely packed, well formed, spherical chondrules (up to 2.4 mm) set within a sparse black matrix. Minerals are olivine, orthopyroxene, chromite, kamacite and troilite. Chondrules contain alkali- and Si-rich glass containing variable amounts of Ca and Fe.

Geochemistry: Olivine (Fa0.4-73.1; Cr2O3 in ferroan examples = 0.07-0.79 wt.%, mean 0.25±0.30 wt.%, N = 15), orthopyroxene (Fs1.2-23.5Wo0.3-1.6, N = 3).

Classification: Ordinary chondrite L3 (group based on magnetic susceptibility); estimated subtype 3.0-3.2 based on ranges, mean values and standard deviations of Fa and Cr2O3 content of ferroan olivines.

Specimens: 10.2 g including one polished thin section at UWB; the remainder is held by Mr. J. Curchin.
