History: Bought by Jean Redelsperger from Lahcen Ait Ha in Erfoud in January 2015.
Physical characteristics: Eight irregular gray fragments without fusion crust. Chondrules are clearly visible at the surface. Cut surface shows closely packed large chondrules, with little weathering.

NWA 13881 est une météorite de type CV3 avec des très gros chondres.
Les chondrites CV3 se caractérisent par la présence de gros chondres, l’abondance en isotopes pré-solaires et des inclusions blanches appelées CAI’s.
Les CAI’s sont des inclusions minérales riches en calcium et en aluminium, formées il y a 4 567 à 4 571 millions d’années elles constituent les matériaux les plus anciens du Système solaire.

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).
