賣家描述
Bechar 008 30.25293 N, 3.53005 W
Bechar, Algeria
Purchased: 2022 Jul
Classification: HED achondrite (Howardite)
History: 据报道,一群陨石猎人于2022年7月在阿尔及利亚的阿拉格拉地区(靠近阿巴德拉)发现了该材料的几块碎片。几个月后,穆罕默德·阿里·洛德从毛里塔尼亚的一家陨石经销商处购买了共计1700 g。
Petrography (K. Metzler, IfP) 多岩质陨石性碎屑角砾岩,由矿物碎片和岩质碎屑块(大小至约5 mm)组成。这些成分镶嵌在细粒碎屑基质中,形成相关碎屑的细粒基质。
Lithic clasts are dominated by eucritic gabbros and granulites, both of which show exsolved pyroxene. 矿物碎屑以欧型辉长岩和颗粒岩为主,两者都显示出排出辉石的结构(exsolution lamellae)。
Mineral fragments include various eucritic pyroxenes (with and without augite exsolution lamellae), diogenitic pyroxene, feldspar, a silica polymorph, chromite, ilmenite, and Fe-Ni metal. 矿物碎片包括多种欧型辉石辉石族矿物(有或无辉长石排出层),狄俄根辉石、长石、一种硅质同晶体、铬铁矿、赤铁矿/针铁矿,以及Fe-Ni金属。 About 10-20 vol% diogenitic components.
Shock stage: moderate
Weathering grade: low
Classifier: K. Metzler, IfP.
This lot has no reserve price and comes with a certificate of authenticity.
