Best Achondrite

Novo Urei is a ureilite meteorite that fell in Penza Oblast, Russia, in 1886. It became the defining specimen of the ureilite class, a group of primitive achondrites composed mainly of silicate minerals with carbon-rich material between the grains. Ureilites commonly contain graphite and microscopic...

Aubres is an aubrite meteorite that fell near Nyons in southeastern France in 1836. It gave its name to the aubrites, a class of enstatite-rich achondrites formed under unusually oxygen-poor conditions and distinguished by their pale, magnesium-rich silicate material. As the type specimen for the gr...

Bunburra Rockhole is a basaltic achondrite meteorite that fell in Western Australia in 2007 and was recovered through observations made by the Desert Fireball Network. Photographic records of its fireball allowed researchers to calculate its atmospheric trajectory and pre-impact orbit, making it the...

Ibitira is a basaltic achondrite meteorite that fell near Martinho Campos in Minas Gerais, Brazil, in 1957. It was historically compared with eucrites because its mineralogy and basaltic texture indicate formation from differentiated planetary material. Its oxygen-isotope composition differs from th...

Pontlyfni is a meteorite that fell near the village of Pontlyfni in Gwynedd, Wales, in 1931. It is classified as a winonaite, a rare type of primitive achondrite whose mineralogy records substantial heating and recrystallization without the complete differentiation seen in many other achondrites. It...

Bustee is an aubrite meteorite that fell in northern India in 1852. Aubrites are rare, highly reduced achondrites composed predominantly of enstatite, with mineral chemistry indicating formation under conditions containing very little oxygen. As a documented nineteenth-century fall, Bustee provides...

An anomalous aubrite found in Lubbock County, Texas, USA, notable for its unique texture suggesting it represents a distinct parent body from all other aubrites.

Peña Blanca Spring is an aubrite meteorite that fell in Brewster County, Texas, in 1946. The fall produced a pale, enstatite-rich achondrite, a rare meteorite type formed under highly reducing conditions and containing very little iron in oxidized minerals. Its observed arrival and substantial recov...

Bishopville is an aubrite meteorite that fell near Bishopville in Sumter County, South Carolina, in 1843. Aubrites are enstatite-rich achondrites, meaning they are igneous meteorites with very little metallic iron and without the abundant chondrules found in ordinary chondrites. As a witnessed ninet...

Havero is a ureilite meteorite that fell in Finland in 1971 and was recovered as a single stone weighing approximately three kilograms. Ureilites are primitive achondrites composed chiefly of olivine and pyroxene, commonly accompanied by carbon in forms that can include graphite and microscopic diam...

An aubrite meteorite found in Russia, notable for containing clasts of differing lithologies, indicating it is a regolith breccia from the aubrite parent body.

A ureilite meteorite found in Assam, India, one of the earliest ureilites recovered from the Indian subcontinent and studied for its distinctive carbon phases.

Mayo Belwa is an aubrite meteorite that fell in Adamawa State, Nigeria, in 1974 and was recovered as a single stone. Aubrites are rare achondrites composed predominantly of nearly iron-free enstatite, indicating formation under highly reducing conditions. Its mineralogy links it to a small, unusual...

A ureilite meteorite found in Roosevelt County, New Mexico, USA, notable for its high carbon content and the presence of both graphite and nanodiamond phases.

An aubrite meteorite that fell in Sudan in 1944, one of the few African aubrite falls and noted for its coarse-grained enstatite texture and low metal content.

A ureilite meteorite found in Uttar Pradesh, India, classified as a carbon-bearing achondrite containing both graphite and trace diamond inclusions.

A ureilite meteorite found in Western Australia, contributing important specimens to the study of carbon-bearing achondrites from the ureilite parent body.
