Quick Summary

An aubrite is a type of achondrite meteorite, meaning it is a stony meteorite that lacks chondrules. These meteorites are characterized by the presence of enstatite, a mineral that forms under highly chemically reducing conditions. Aubrites are believed to have formed within asteroids that experienced melting and crystallization processes. They are a relatively rare group, making up a small percentage of all known meteorites. The name "aubrite" comes from the Aubres commune in France, where a meteorite containing this type of material fell in 1836.123

Achondrites
…asteroidal achondrite groups are the aubrites, the howardite-eucrite-diogenite association, and the ureilites. Aubrites are also known as enstatite achondrites. Like the enstatite class of chondrites, the aubrites derive from parent bodies that formed under highly chemically reducing conditions. As a result, they contain elements in the form of less-common compounds—for…
