History: The meteorite was purchased from a Moroccan meteorite dealer at the mineral fair in Munich, Germany.

Physical characteristics: Three small individuals partly covered with fusion crust were recovered from the north-African Sahara.

Petrography: The meteorite is a fine-grained breccia with basaltic, impact melt and mineral clasts set into a clastic matrix. Exsolved pyroxene and plagioclase are the most abundant minerals. Minor phases include chromite, pyrrhotite and SiO2 polymorphs.

Geochemistry: low-Ca pyroxene: Fs61.2±1.7Wo2.1±0.5 (Fs58.8-64.5Wo1.7-3.7, n=19), FeO/MnO=30-35; Ca-pyroxene: Fs28.6±2.3Wo41.8±2.6 (Fs25.2-35.9Wo37.9-46.2, n=20), FeO/MnO=31-35; calcic plagioclase: An88.9±4.1 (An75.1-93.1, n=20)
