Writeup from MB 92:
Al Haggounia 001 N27°30',W12°30'
Al Haggounia, Morocco
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).
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.
