Writeup from MB 106:
Northwest Africa 8355 (NWA 8355) (Northwest Africa) Purchased: 2014 Feb Classification: Ordinary chondrite (L3) History: Purchased by Marcin Cimała in February 2014 from a Moroccan dealer. Petrography: (A. Irving and S. Kuehner, UWS) Closely-packed, medium-sized (apparent diameter 600±200 μm), well-formed chondrules. Minerals are olivine, orthopyroxene, subcalcic augite, sodic plagioclase, altered kamacite, troilite, chromite and taenite. Geochemistry: Olivine (Fa15.8-25.5, N = 5; Cr2O3 content of ferroan olivine <0.02 wt.%), orthopyroxene (Fs11.9-35.4Wo0.4-4.3, N = 3), subcalcic augite (Fs11.0-26.6Wo34.8-27.0, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.65. Classification: Ordinary chondrite (L3). Subtype estimated to be L3.8 based on the limited range in fayalite content of olivine and paucity of Cr2O3 in ferroan olivine (Grossman and Brearley, 2005). Specimens: 20.2 g including one polished thin section at UWB. The remainder is held by M. Cimała. | ||||||||||||||||||||||||||||||||
