Writeup from MB 109:

Northwest Africa 13466 (NWA 13466)

(Northwest Africa)

Purchased: 2019

Classification: Carbonaceous chondrite (CK6)

History: The meteorite was bought by the main mass holder from an Algerian meteorite dealer.

Physical characteristics: Two dark brownish rocks without fusion crust.

Petrography: The meteorite displays a brownish partly reddishly stained interior and is predominantly composed of fine-grained recrystallized matrix dominated by ferrous olivine. Only few chondrules were encountered. Minor phases include low-Ca pyroxene, Ca-pyroxene, intermediate plagioclase, and FeNi-sulfides. Cr-rich magnetite is abundant; metal is virtually absent.

Geochemistry: olivine: Fa31.5±0.5 (FeO/MnO=108±9, n=12); low-Ca pyroxene: Fs27.0±0.3Wo1.8±0.8, n=2; Ca-pyroxene: Fs9.4±0.5Wo46.3±0.2, n=9
