Physical characteristics: Weathered exterior; saw cut reveals dark brown crystals ~2 mm in diameter. Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows numerous pyroxene grains some of which are up to 2000 μm, finer-grained (50-200 μm) olivines are also present. Numerous metal and iron oxide veinlets throughout. Kamacite and troilite detected, plagioclase is absent. Geochemistry: (C. Agee and N.
