Classification: EL chondrite impact melt rock, vesicular
Place/Time: 2006 in Al Haggounia, Morocco
Mass: 3 tons

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).
NOTE: Slices comes from 118kg single specimen (fragment) that was found in 2019 and purchased by me in january 2020. Both side polished, 4mm thin.
