History: Several tons of this material have been found on the ground or by digging near Al Haggounia, Morocco (Chennaoui et al. 2007) for description of the strewn field) and sold to several dealers. 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. Type specimens: A total of 50 g of sample and three polished sections are on deposit at UPVI. Main masses: Beroud, 3886 g (26 pieces from 1185 g to 5.8 g); PThomas, 4497 g (33 pieces from 11 to 1507 g); Hmani, about 500 kg; Ouzrou, about 500 kg.

History: Purchased by Marcin Cimała in May 2009 from a Moroccan dealer. Physical characteristics: A group of dark brown, dense stones comprising two larger pieces and many small fragments (total 1088 g). Fresh interiors are black with abundant, anastomosing metal and sulfide grains. Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of clasts rich in irregular, elongated grains of metal and sulfides with associated Fe-poor silicates. Minerals are forsterite, enstatite, diopside, albite, Si-poor kamacite, troilite, taenite, schreibersite, and daubreelite. Geochemistry: Forsterite (Fa0.9), enstatite (Fs1.5-1.8Wo1.4-1.2), diopside (Fs0.7-2.3Wo45.9-44.6). Classification: EL-melt breccia. Specimens: A total of 36 g of type material and one polished thin section are on deposit at UWB. The remaining material is held jointly by Mr. M. Cimała and Mr. T. Jakubowski.
