A single piece was found in 2014 in Algeria. The piece was transported to Mauritania and from there to Morocco. The piece was purchaced from Rachid Chaoui, a Moroccon meteorite dealer on the January 2015. Meteorite was send on the February 2015 to Karl Morizt for cutting an analysis piece. The piece was send for analysis to Carl Agee a professor of Earth and Planetary Sciences in the University of New Mexico.
Single stone. A saw cut reveals a feldspathic breccia with dark-gray shock melt veins.
(C. Agee, UNM) This meteorite is dominated by feldspathic-rich domains of fine-grained crystals and larger plagioclase fragments. Abundant shock melt veins are present, some with vesicles. Accessory troilite and ilmenite were observed.
