Writeup from MB 103:
Northwest Africa 8133 (NWA 8133) (Northwest Africa) Purchased: 2013 Oct Classification: Ordinary chondrite (L3) History: Purchased by Adam Aaronson in Temara, Morocco in October 2013. Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely-packed, well-formed, medium-sized (0.3-1.6 mm, mean 1.0±0.5 mm) chondrules. Minerals are olivine, orthopyroxene, pigeonite, subcalcic augite, sodic plagioclase, altered kamacite, chromite and troilite. Geochemistry: Olivine (Fa3.9-31.4, N = 9; Cr2O3 in ferroan examples = 0.04-0.17 wt.%, mean 0.09 wt.%, sd = 0.05 wt.%, N =7), orthopyroxene (Fs4.1-26.5Wo0.5-3.7, N = 3), pigeonite (Fs6.3Wo8.4), subcalcic augite (Fs4.5Wo33.1). Classification: Ordinary chondrite L3. Estimation of subtype 3.5 based on histograms of Cr2O3 distribution in ferroan olivine given in Fig. 4 of Grossman and Brearley (2005). Specimens: 21.9 g including one polished thin section at UWB. The remainder is held by Aaronson. | ||||||||||||||||||||||||||||||
