Northwest Africa 11085 (NWA 11085)(Northwest Africa)Purchased: 2015Classification: Carbonaceous chondrite (CO3.0)Physical characteristics: Dark brown stones. Cut surface reveals a brownish interioe.Petrography: Chondrules (some with dust rims, average apparent diameter 270 µm, N=47), small CAIs in a fine-grained matrix. Opaques are metal (mostly replaced by weathering products) and sulfides. Modal abundances: chondrules and fragments 46 vol%25, matrix 38 vol%25, opaques 16 vol%25 (from point counting, N=104).Geochemistry: Olivine Fa range 0.8-48.6, average Fa27.6±17.9, PMD 59%25, FeO/MnO=98 (N=14), Cr2O3 on ferroan olivine 0.29±0.13 wt%25 (N=11). Orthopyroxene Fs1.8±0.4Wo1.5±0.5 (N=5). Magnetic susceptibility log ? (× 10-9 m3/kg) = 4.84.Classification: CO3.0. Subtype from olivine Fa PMD, range, and Cr2O3 content. Strong weathering. Possibly paired with NWA 7892.Specimens: Type specimen at CEREGE. Main maiss with Kuntz.Data from:
