Northwest Africa 14124 (NWA 14124) (Northwest Africa) Purchased: 2021 Apr Classification: HED achondrite (Howardite) History: The meteorite was purchased from a dealer in Morocco. Physical characteristics: Grayish rock partly covered with fusion crust. Petrography: The meteorite is a polymict breccia composed of lithic and mineral clasts set into a more fine-grained clastic and related matrix. Lithic clasts are fine- and coarse-grained basaltic and dark impact melts up to 6 mm in size. Main minerals are up to 9-mm-sized diogenetic orthopyroxene (about 15%), compositionally zoned low-Ca pyroxene, exsolved pyroxene and calcic plagioclase. Minor phases include silica, Ti-bearing and Ti-free chromite, ilmenite, FeS, and kamacite. Geochemistry: Eucritic low-Ca pyroxene: Fs50.7±0.4Wo2.6±0.3 (Fs50.2-51.3Wo2.1-2.9, n=5, FeO/MnO=29-30); augite exsolution lamellae: Fs21.4±0.2Wo44.4±0.2 (Fs21.2-21.7Wo44.1-44.7, n=5, FeO/MnO=25-28); diogenetic low-Ca pyroxene: Fs21.4±1.4Wo2.8±0.4 (Fs19.7-23.0Wo2.4-3.4, n=10, FeO/MnO=24-30); zoned low-Ca-pyroxene: Fs27.5±5.6Wo2.0±0.1 (Fs22.0-36.9Wo1.9-2.1, n=5, FeO/MnO=29-32); calcic plagioclase: An86.1±7.5 (An72.8-92.9, n=7) | ||||||||||||||||||||||||||||
