Saw-cut shows white feldspathic clasts and a few dark colored clasts set in a dark gray matrix. There a few, very small, metal grains visible. Petrography: (C. Agee, UNM) This meteorite is a fine-grained lunar feldspathic regolith breccia with numerous agglutinates, shock melt zones and impact melt clasts present. Many of the agglutinates and melt veins are heavily vesiculated. There are also many fragmental feldspar grains and some microgabbros present, a few of these fragments are up to several mm in size. Accessory Fe-Ni metal, Fe-sulfide, chromite, and ilmenite are present. Weathering products iron oxide, barite, and calcite were detected. Geochem: (C. Agee and N.
