From the MetBul:
Physical characteristics: Single stone with patches of black fusion crust. The exposed interior is a fragmental breccia with coarse light-green to cream-colored grains. Scattered oxidized metal grains are visible throughout.
Petrography: (A. Ross and C. Agee, UNM) Reflected light microscopy images give the approximate modal abundances: 80% olivine, 15% pyroxene, 1-2% troilite, with minor chromite, taenite, kamacite, silica, and schreibersite. No plagioclase detected.
Classification: Ungrouped achondrite, peridotite breccia. Similar to NWA 12217, possibly paired with NWA 12562, NWA 12319, and NWA 13954.
