History: The meteorite was bought in 2008 from a Moroccan meteorite dealer on a mineral fair in Bruegg, Switzerland.

Petrography: The meteorite is a breccia consisting of fine- and more coarse-grained basaltic clasts set into a clastic groundmass of dominantly calcic plagioclase and exsolved pyroxene. Plagioclase grains are up to 1.5 mm in size. Minor phases are ilmenite, chromite and silica.

Geochemistry: low-Ca pyroxene: Fs61.9±0.8Wo2.1±0.9 (Fs60.3-62.9Wo1.5-4.0, n=11, FeO/MnO=29-33); Ca-pyroxene: Fs30.4±2.0Wo40.4±2.3 (Fs27.4-33.4Wo36.3-44.6, n=22, FeO/MnO=28-35); calcic plagioclase: An90.1±0.8 (An89.0-91.8, n=23)
