[show all] Comments: Approved 30 Jul 2023 Writeup Writeup from MB 112: Northwest Africa 15893 (NWA 15893) (Northwest Africa) Purchased: 2022 Classification: Enstatite chondrite (EH6) History: The meteorite was purchased from a meteorite dealer in Morocco. Physical characteristics: Dark brownish rock with some fusion crust. Petrography: The meteorite displays a fine-grained granular texture dominated by 20 to 300 µm sized enstatite and sodic feldspar grains. Opaque phases are Si-bearing kamacite, schreibersite, troilite, daubréelite, niningerite, and Cr-bearing troilite. No relict chondrules detected. Geochemistry: enstatite: Fs0.3±0.2Wo0.6±0.03 (Fs0.2-0.6Wo0.6-0.7, n=10); feldspar: An7.5±0.4Ab89.0±0.8Or3.5±0.7 (An7.0-7.9Ab88.1-90.3Or2.7-4.5, n=7); kamacite: Ni=6.48±0.15, Si=3.40±0.06, Co=0.29±0.01, n=5; troilite: Cr=0.77±0.18, Ti=0.24±0.017, n=5; (Mg,Fe,Mn)S: Fe=16.2±0.3, n=5 (all wt%) Classification: Enstatite chondrite (EH6a). EH designation based on silicon content in kamacite and presence of niningerite.
