History: Purchased by team eegooblago (Brahim Tahiri, Dustin Dickens and Sean Tutorow) while on expedition in Northwest Africa and Western Sahara in April and May 2015.

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.

Geochemistry: (C. Agee and N. Muttik, UNM) Pigeonite Fs_49.5±9.2Wo_15.7±3.3, Fe/Mn=36±3, n=31; augite Fs_28.4±6.7Wo_33.3±2.0, Fe/Mn=32±3, n=33; maskelynite An_53.8±1.7Ab_44.2±2.0Or_2.1±0.7.
