NWA 13135 (Paired) - Ureilite (Primitive Achondrite)

NWA 13135 is a rare Ureilite purchased in Morocco in 2019 after recovery from Northwest Africa. 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 13135 is officially classified as a Ureilite, with a recorded total known weight of 58.3 g, making the officially classified material very limited. Material described as ‘paired’ should be presented as closely matching NWA 13135 in character and classification unless supported by direct documentation under the official name.

NWA 13135 specimens are typically dark, stony Achondrite material, and some individuals show attractive flow-lined fusion crust over part of the surface. 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 through shock processes, making the group especially interesting among Achondrites.

Studying NWA 13135 and paired material 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, low official mass, and strong scientific appeal. Each specimen represents ancient asteroid material shaped by heat, shock, and rapid cooling in the early solar system.
