Writeup from MB 105:
Northwest Africa 10512 (NWA 10512) Morocco Purchased: Dec. 2015 Classification: Carbonaceous chondrite (CK4) History: Purchased by Ke Zuokai in Dec. 2015 from a Moroccan dealer. Physical characteristics: One single stone. No fusion crust. Minimal weathering. Petrography: A few chondrules set into abundant fine-grained matrix. Fe-rich olivine is the dominant mineral phase. Pyroxene usually is Ca-rich, and plagioclase is Na-rich. Accessory phases include Cr-bearing magnetite and sulfide. This sample does not have metallic FeNi, but contains a few Ni-bearing magnetite. No large CAIs were observed in this sample. Geochemistry: Olivine (Fa31.5-35.0, Fe/Mn 90-125), Augite (Fs9.1-16.8Wo44.4-49.9), pigeonite (Fs25.8Wo4.6), Plagioclase (Ab60.1-70.5Or1.4-3) Classification: CK4. This sample is classified as type 4 because the compositional range of olivine is slightly more heterogeneous (PMD of Fa content of olivine is about 5.8%) than those in type 5. | ||||||||||||||||||||||||||||||
