History: A meteorite hunting expedition to the was organised by J. Redelsperger, Claude Roy and guided by Ali Oulmaleh on April 2013. They met Lahcen Oukhouya, who found a 332.85 g meteorite in Chwichiya area, around 120 NE of Laayoune. He was prospecting in this area because of the report of a 219 g eucrite in the same area. Then the other pieces were found by Lahcen and other hunters.

Physical characteristics: Several uncrusted, coarse-grained stones. The interior is brecciated with clear clasts embedded in a dark matrix, showing a doleritic texture.

Petrography: Breccia with coarse basaltic clasts in a fine-grained matrix. The matrix has a doleritic texture with plagioclase grain size of several mm. Dominant minerals are exsolved pyroxene and mm-sized calcic plagioclase laths. Minor phases include chromite, silica, Ca-Phosphate, troilite and metal.

Geochemistry: Pyroxenes: Low-Ca Fs59.9±2.5Wo3.7±1.8 (Fs58.2-62.7 Wo1.7-5.6 N=6 FeO/MnO=33.4±2.8); Ca-Px Fs26.7±1.3Wo42.3±2.1 (N=2 FeO/MnO=33.8±3.6). Plagioclase: An89.2±0.7, N=2.

Classification: Eucrite, breccia.
