History: The meteorite was purchased from a meteorite dealer in Morocco.

Physical characteristics: Brownish rock with some fusion crust.

Petrography: The meteorite displays a light brownish to orange interior and is composed of sparse up to 1 mm sized angular type 3 clasts and matrix. Olivine and low-Ca pyroxene are compositionally unequilibrated in clasts and matrix; Fe-rich olivine is the most dominant mineral phase in the matrix. Chondrules have an average diameter of about 400 μm. More minor phases include low-Ca pyroxene, rare Ca-pyroxene, sodic plagioclase, sulfides, and Ti-bearing chromite; no metal has been detected.
