Writeup from MB 105:

Northwest Africa 10264 (NWA 10264)

(Northwest Africa)

Purchased: 2015 Feb

Classification: Ordinary chondrite (LL(L)3)

History: Purchased by Gary Fujihara in February 2015 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Closely packed, well-formed chondrules (apparent diameter up to 2.7 mm) are set in a sparse, finer grained matrix containing altered metal. Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.38.

Geochemistry: Olivine (Fa0.8-67.0; Cr2O3 in ferroan examples = 0.15-0.28 wt.%, mean 0.22±0.05 wt.%, N = 6), orthopyroxene (Fs1.7-6.5Wo0.5-0.6, N = 3), subcalcic augite (Fs6.6Wo24.0), augite (Fs1.2Wo38.3).

Classification: Ordinary chondrite LL(L)3. The range in Fa content in olivine and the Cr2O3 contents in ferroan olivine are consistent with a relatively low subtype (estimated to be 3.3 to 3.4).

Specimens: 20.4 g including one polished thin section at UWB; main mass with Mr. G. Fujihara.
