Writeup from MB 110:
Northwest Africa 14417 (NWA 14417) Mauritania Find: 2020 Classification: Carbonaceous chondrite (CVox3) History: Found in Spring 2020 in northeast Mauritania by some soldiers and subsequently sold to a Mauritanian meteorite dealer. Later purchased in Fall 2020 by Geologist Juan Avilés Poblador. Physical characteristics: Single stone with slightly weathered fusion crust. Petrography: (D. Sheikh, Cascadia) This sample contains chondrules (Av. 1.0 mm, up to 2.5 mm; ~50 vol. %) and CAIs set within a mostly opaque, fine-grained matrix (~ 50 vol. %) containing accessory magnetite and Ni-bearing sulfides. Geochemistry: Olivine (Fa25.1±14.7, range Fa6.9-49.9, n=10), Low-Ca Pyroxene (Fs5.2±3.9Wo2.4±1.3, range Fs1.2-8.9Wo0.9-3.4, n=5). Sulfides have average Ni content 11.5±5.2 wt% (n=4). Classification: Carbonaceous chondrite (CVox3). The mineral compositions and texture indicate classification as a CV3. The magnetic susceptibility and Ni concent of sulfides indicate classification to the Bali subgroup of oxidized CV3 chondrites Gattacceca et al., 2020. Specimens: 9.03 grams and a thin section at Cascadia; main mass with Juan Avilés Poblador. | ||||||||||||||||||||||||||||||
