HED group meteorites – HED gruppe meteoritter

HED meteorites are achondrites that are similar to terrestrial igneous rocks. They are thought to have originated from the asteroid Vesta. There are three subgroups: Howardites, Eucrites, and Diogenites. These differ in mineral composition and texture, which were determined by their history while still part of the crust of Vesta.

Howardites are brecciated mixtures of diogenite and eucrite material. Eucrites are basaltic rocks comprised of pigeonite and plagioclase feldspar, with minor phosphate, metal, troilite, silica, and ilmenite, and come in several different types based on their textures. Diogenites are coarse-grained orthopyroxene-rich rocks, generally ~ 90% orthopyroxene, and contain minor amounts of olivine, chromite, plagioclase, clinopyroxene, and opaque minerals such as troilite and metal.
