(Northwest Africa)
Purchased: 2015
Classification: Lunar meteorite (feldspathic breccia)
History: Purchased by Darryl Pitt from a Moroccan meteorite dealer, reportedly found in Mauritania near the Algerian border.
Physical characteristics: Weathered irregular exterior. Saw cuts reveal a fragmental breccia with numerous feldspathic and mafic clasts set in a gray groundmass.
Petrography: (C. Agee,UNM) This meteorite is a very heterogeneous polymict breccia consisting of numerous microgabbro clasts, shock melt pools and veins, fragmental plagioclase, pyroxene, and olivine. Accessory Fe-oxide, troilite, Ti-chromite, ilmenite, and silica were observed. Thin calcite weathering veins are present.
