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.

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.
