Lunar looks-like Eucrite with a low total mass of 835 grams. Coarse-grained eucritic clasts with ophitic to subophitic textures and mineral fragments (pyroxene, plagioclase, silica polymorph) set in a dark gray matrix. The matrix represents a crystallized melt with subophitic texture consisting of pyroxene and skeletal plagioclase crystals. Lithic clasts and mineral fragments are strongly recrystallized. Some pyroxene fragments contain Fe-rich olivine veins. Accessories are ilmenite, troilite, and metal (mostly oxidized). Calcite veins occur. Backscattered electron (BSE) images provided by Dr. Knut Metzler.
