賣家描述
Ain Ben Tili 004 25.46857 N, 10.13846 W
蒂里斯-泽姆穆尔，毛里塔尼亚
Find: 2022
Classification: 未分组无球粒陨石
History: The meteorite was found 2022 in northern Mauritania and subsequently purchased by Mohamed Ali Loud from Alian Muftah at the 2024 Munich mineral fair.
物理特征: 许多灰白色碎片，其中一些部分被黑色熔融地壳覆盖。
Petrography: Achondritic breccia composed of a great variety of up to 7 mm sized euhedral to subhedral mineral fragments in a fine-grained cataclastic matrix of related material. Most abundant are compositionally homogeneous olivine (about 85 vol%), exsolved pyroxene (about 8 vol%) and feldspar (about 2 vol%) grains. Zoned olivines are rare. Accessories (about 5 vol%) include silica, chromite, FeS, kamacite, and taenite. Contains augite-chromite symplectites.
岩石学：无球粒陨辉长岩，由多种晶粒尺寸可达7 mm的单晶到半晶晶粒组成，嵌于相关物质的细粒断裂基质中。最丰富的是组成均匀的橄榄石（约85体积%）、共格排布的辉石（约8体积%）和长石（约2体积%）晶粒。Zoned橄榄石较少。配晶相（约5体积%）包括二氧化硅、铬铁矿、FeS、镍镲铁、等。含有辉辉石-铬铁矿协晶体。
