Diogenite

The Johnstown Diogenite.

Tatahouine, diogenite

Diogenites are a subgroup of the HED meteorite group, a type of achondritic stony meteorites.

Origin and composition

Diogenites originates from deep within the crust of the asteroid 4 Vesta, and as such are part of the HED meteorite group. There are about 40 distinct members known.

Diogenites are composed of igneous rocks of plutonic origin, having solidified slowly enough deep within Vesta's crust to form crystals which are larger than in the eucrites. These crystals are primarily magnesium-rich orthopyroxene, with small amounts of plagioclase and olivine.^[1]

Name

Diogenites are named for Diogenes of Apollonia, an ancient Greek philosopher who was the first to suggest an outer space origin for meteorites.^[2]
