History: A single stone of 10.5 g partly covered with fusion crust was found in the western Sahara in Morocco in 2004. Petrography: (A. Greshake, MNB) A polymict breccia consisting of basaltic and mineral clasts set into a fine-grained groundmass with mineral fragments that are dominantly large plagioclase and exsolved Ca pyroxene. Minor phases include silica, troilite, and ilmenite.

Geochemistry: Plagioclase (An79–91.4), pyroxene (Fs26.6–61.2Wo2.6–42.5).
