Northwest Africa 13282 (NWA 13282) Western Sahara Find: 2018 Classification: Ordinary chondrite (L3) History: Found in Western Sahara in late 2018. Purchased on January 11, 2019, by John Higgins from a meteorite dealer in Morocco. Physical characteristics: Single stone with dark-brown fusion crust. Petrography: (D. Sheikh, FSU) Sample is a chondrite composed of well-defined chondrules (Av. 750±50 µm) set in a dark, fine-grained matrix containing silicates, Fe-Ni metal, troilite, and chromite. Most chondrules contain devitrified mesostasis. Geochemistry: Olivine (Fa22.1±5.7, range Fa3.1-28.7, n=26), Low-Ca Pyroxene (Fs14.0±5.8Wo0.8±0.5, range Fs2.2-20.4Wo0.2-2.2, n=16). Classification: Ordinary Chondrite (L3) due to chondrule size, Fa,Fs heterogeneity, and magnetic susceptibility.
