Writeup from MB 102:

Northwest Africa 8002 (NWA 8002)

(Northwest Africa)

Purchased: 2013 Jun

Classification: Ordinary chondrite (L3)

History: Purchased by Darryl Pitt in June 2013 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed, medium-sized (0.3-1.6 mm) chondrules. Olivine, orthopyroxene, subcalcic augite, augite, sodic plagioclase, chromite, altered kamacite and troilite. .

Geochemistry: Olivine (Fa1.0-49.9; Cr2O3 in ferroan examples is 0.06-0.20 wt.%, mean 0.11±0.05 wt.%, N = 7), orthopyroxene (Fs3.5-40.3Wo0.5-2.4), subcalcic augite (Fs5.8Wo34.2), augite (Fs9.5Wo45.1).

Classification: Ordinary chondrite (L3.5). Estimation of subtype based on histograms of Cr2O3 distribution in ferroan olivine given in Fig. 4 of Grossman and Brearley (2005).

Specimens: 17.8 g and one polished thin section are at UWB. The remainder is held by DPitt.
