North West Africa 13466 (NWA 13466)
(Northwest Africa)
Purchased: 2019
Classification: Carbonaceous chondrite (CK6)
History: The meteorite was purchased by the principal holder of the mass from an Algerian meteorite dealer.
Physical Features: Two dark brownish rocks with no fusion crust.
Petrography: The meteorite has a brownish interior partially tinged with reddish and is composed primarily of a fine-grained recrystallized matrix dominated by ferrous olivine. Only a few chondrules were encountered. Minor phases include low-Ca pyroxene, Ca-pyroxene, plagioclase intermediate, and FeNi sulfides. Cr-rich magnetite is abundant; the metal is practically absent.
Geochemistry: olivine: Fa31.5±0.5 (FeO/MnO=108±9, n=12); low Ca pyroxene: Fs27.0±0.3 Wo1.8±0.8, n=2; Ca-pyroxene: Fs9.4±0.5Wo46.3±0.2, n=9
