NWA 13947 - Ureilite (Primitive Achondrite)

NWA 13947 is a rare Ureilite purchased in January 2021 from a meteorite dealer in Nouadhibou, Mauritania. Ureilites are unusual Achondrite meteorites, rich in olivine and pyroxene, and are thought to come from a partially differentiated parent body that experienced heating, disruption, and rapid cooling. NWA 13947 is officially classified as a Ureilite, placing it within one of the more distinctive and scientifically interesting Achondrite groups. 

 

NWA 13947 is described as a brownish rock without fusion crust. As a Ureilite, it lacks chondrules and instead records igneous and thermal processing on its parent body. Ureilites are also known for carbon-bearing phases, which can include graphite and, in some cases, diamond formed by shock processes, making the group especially intriguing among Achondrites. Its texture and mineralogy set it apart from more familiar Chondrites and basaltic Achondrites.

 

Studying NWA 13947 provides insight into partial differentiation, impact disruption, and the unusual history of the Ureilite parent body. For collectors, it offers a scarce Northwest African Ureilite with recognised classification, recent recovery history, and strong scientific appeal. Each specimen represents ancient asteroid material shaped by heat, shock, and rapid cooling in the early solar system.
