Writeup from MB 107:
Northwest Africa 12366 (NWA 12366) (Northwest Africa) Purchased: April 2018 Classification: Carbonaceous chondrite (CO3) History: Bought in April 2018 from a dealer in Zagora, Morocco. Petrography: (A. Bischoff, IfP) Chondrules, chondrule fragments, and CAIs are embedded in a fine-grained brownish matrix, which has an abundance of about 20-30 vol%. The majority of chondrules contain Fe-poor olivine and low-Ca pyroxene and the mean apparent chondrule size is about 200 µm. Geochemistry: (K. Klemm; A. Bischoff, IfP) Mineral compositions and geochemistry: Random measurements of olivine grains revealed Fa11.9±14.0 (Fa0.4-49.4); n=14. Random measurements of low-Ca pyroxene grains revealed Fs2.3±1.3Wo1.7±1.5 (Fs1.1-5.7Wo0.3-5.1); n=12. Classification: CO3 chondrite based on small chondrule size, chondrule-matrix ratio, texture, and mineral chemistry. | ||||||||||||||||||||||||||||||
