Writeup from MB 107:
Northwest Africa 11802 (NWA 11802) (Northwest Africa) Purchased: 2017 Jun Classification: Ordinary chondrite (L3) History: Purchased by Gary Fujihara in June 2017 from a Moroccan dealer. Petrography: (A. Irving and S. Kuehner, UWS) Closely-packed unequilibrated chondrules (apparent diameter 620 ± 410 µm, N = 18) are set in a sparse fine grained matrix containing stained metal. Geochemistry: Olivine (Fa0.6-81.6, Cr2O3 in ferroan examples 0.06-0.28 wt.%, mean 0.12±0.06 wt.%, N = 9), orthopyroxene (Fs1.5-23.3Wo0.2-3.4, N = 3), subcalcic augite (Fs14.6Wo26.6), augite (Fs5.4Wo45.4). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.76. Classification: Ordinary chondrite (L3). The ranges of Fa content in olivine and of Cr2O3 content in ferroan olivine indicate a relatively low petrologic subtype between 3.3 and 3.5. Specimens: 20.5 g including one polished thin section at UWB; remainder with Mr. G. Fujihara. | ||||||||||||||||||||||||||||||||
