Physical characteristics: Six indentical appearing stones with no fusion crust. Saw-cut surfaces show an intergranular mix of light-green pyroxene and maskelynite. Dark colored melt veins and pockets are prominent, with most showing significant vesiculation. Petrography: (C. Agee, UNM) This meteorite consists of ~50% pyroxene, ~30% maskelynite, and ~15% shock melt. Pyroxenes show igneous zoning, and some are partially melted from shock. Shock melt domains are up to 1 cm wide and many contain vesicles 1-3 mm in diameter. All plagioclase has been transformed to maskelynite. Fe-sulfide, Ti-magnetite, ilmenite, and silica observed.
