Its unique composition and origin make it a rare and sought-after piece among meteorite collectors. This meteorite is a clast-rich polymict breccia with lithic fragments embedded in a fine-grained moderately vesiculated groundmass. Fragmental clasts sizes range from <0.1-6 mm and are primarily basaltic. Kamacite, Cr-spinel, silica, troilite, and ilmenite are present. This meteorite is shocked with some impact melt textures present. Name: Northwest Africa 14685 This is an OFFICIAL meteorite name.
