Physical characteristics: Deep gray rock with some fusion crust
Petrography: Eucrite-melt breccia composed of up to 3 cm sized basaltic clasts and up to 500 µm sized mineral fragments in black shock melted matrix. Main minerals are exsolved pyroxenes and calcic plagioclase. The shock melt is mostly finely recrystallized and partly displays flow textures. Mineral grains entrained in the melt matrix often show resorption textures. Minor phases include silica, chromite, ilmenite, and FeS. No metallic iron detected.
