A magnificent collector’s item, this unclassified chondrite was discovered in the Sahara, most likely in Morocco.
What makes this piece unique is its weight, but also the regmaglypts on its surface.
Regmaglypts are hollow indentations, often thumb-shaped, found on certain meteorites.
Entering the atmosphere slows down the trajectory of meteorites due to air friction.
This friction tears off pieces, forming regmaglypts.
History: Found by Ahmed Dich and Hssain Azmamar in January 2021. Bought by Jean Redelsperger from Zaid Oualguirah in February 2021.
Physical characteristics: Partially crusted stone with a light grey interior
Petrography: (J.Gattacceca, CEREGE) Brecciated igneous rock with mineral and lithic gabbroic clasts. Main minerals are pyroxene (some exsolved) and plagioclase with grain size in the 100 to 500 µm range. Accessory minerals: metal (to 150 µm), chromite (to 100 µm), ilmenite (to 150 µm), troilite (to 200 µm).

Al Haggounia 008 is an ordinary chondrite of 6.270 kg composed of 31 fragments.
This meteorite was found in December 2013, 120 km northeast of Laayoune in the Western Sahara, in a place called Chwichiya (little fez) in reference to the mountain seen in this area in the shape of a fez.
Chwichiya is an area rich in meteorites. The pieces on sale have not been cleaned by choice, they are sold as they were found. These are the last pieces on sale!
