Writeup from MB 111:
Northwest Africa 15298 (NWA 15298) (Northwest Africa) Purchased: 2022 Classification: Carbonaceous chondrite (CM2) History: The meteorite was reportedly found 2021 in the Erg Chech region, Algeria and subsequently purchased from a local meteorite dealer. Physical characteristics: Several small, almost black fragments partly covered with fusion crust Petrography: Brecciated carbonaceous chondrite composed of small (apparent mean diameter about 250 μm) chondrules, chondrule pseudomorphs, mineral fragments, and rare CAIs set into abundant fine-grained matrix. Some components are surrounded by fine-grained dust rims. The Fe-rich matrix contains abundant sulfides and Ca-carbonates. Geochemistry: Matrix analyses yield FeO=37.8±4.8 wt% and an average total of 86.2±1.5 wt% (5 µm defocused beam, N=10), the latter indicating the presence of hydrous minerals. | ||||||||||||||||||||||||||||||
