The coordinates are given for the center of the strewn field, which extends ~ 40 km. Physical characteristics: It is impossible to assess precisely the amount of material already (and to be) recovered, but according to dealers, collectors, and Jambon it is about 3 metric tons composing many samples of varied sizes (from a few g to 50 kg). The largest stones were recovered after excavating them from the ground. The outer surface is rusty brown due to severe alteration. Looks like a sedimentary breccia cemented by iron oxide and carbonate. Color changes from bluish gray to rusty brown closest to the fractures are observed. Yellow patches of sulfur (alteration) are widespread. The rocks are significantly porous with pore sizes from several cm to hundreds of microns. Petrography: (A. Jambon, O. Boudouma and D. Badia. UPVI) Dominated by enstatite and plagioclase. Troilite, graphite daubreelite, oldhamite, kamacite rich in Si and schreibersite are present. Mineral compositions: Enstatite (En98Fs1Wo1) and plagioclase (Ab78An16Or5). Classification: Achondrite (aubrite); extensive weathering. Similar to and likely paired with NWA 002, 1067, 2736, 2828, 2965.
