Bechar 008 30.25293 N, 3.53005 W
Bechar, Algeria
Purchased: 2022 Jul
Classification: HED achondrite (Howardite)
History: 据称，一群陨石猎人在阿尔及利亚的一个名为Alagla（靠近Abadla）的地区于2022年7月发现了该材料的若干碎片。几个月后，Mohamed Ali Loud从毛里塔尼亚的一名陨石商处购买了总量1700 g。
Petrography (K. Metzler, IfP) Polymict achondritic breccia, consisting of mineral fragments and lithic clasts up to ~5 mm in size. These components are embedded in a fine-grained clastic matrix of related debris. Lithic clasts are dominated by eucritic gabbros and granulites, both of which show exsolved pyroxene. Mineral fragments include various eucritic pyroxenes (with and without augite exsolution lamellae), diogenitic pyroxene, feldspar, a silica polymorph, chromite, ilmenite, and Fe-Ni metal. About 10-20 vol% diogenitic components.
Geochemistry: Mineral compositions and geochemistry: Gabbro clast: Low-Ca pyroxene (host): Fs60.6±0.5 Wo3.1±0.2 (Fs59.9-61.2 Wo2.8-3.3); mean Fe/Mn (at.): 30.3; n=6. Ca-rich pyroxene (exsolution lamellae) Fs28.8±1.4 Wo40.9±1.5 (Fs27.4-30.5 Wo38.8-42.6); mean Fe/Mn (at.): 31.5; n=6. Plagioclase: An86.8±1.8 Or0.3±0.3 (An85.4-89.4 Or0.0-0.8); n=6. Diogenitic pyroxene: Fs22.5±0.5 Wo2.0±0.3 (Fs21.5-23.2 Wo1.5-2.4); mean Fe/Mn (at.): 32.6; n=7. Plagioclase fragments from clastic matrix: An89.6±3.6 Or0.5±0.4 (An82.5-95.7 Or0.1-1.1); n=11.
Classification: Howardite, 基于矿物化学、eucritic岩相的多样性，以及diogenitic组分占>10体积百分比的出现。
