Ureilite

Stone Museum of Geology

The ureilite class of meteorites is named after the type example Novo-Urei, Russia that fell in 1886. Ureilites contain olivine and pyroxenes with graphite and iron filling the intergranular spaces. Rarely, the carbon in the graphite forms tiny diamond crystals. This specimen was found by nomads crossing the Grand Erg Occidental near the Moroccan/Algerian Border in 2007. Date of fall is unknown.
