Northwest Africa 12513 (NWA 12513). Classification: HED achondrite (Eucrite, monomict). Very fresh monomict gabbroic eucrite. Specimen composed of coarse grained lithic clasts in a sparse matrix of related crystalline debris. Major minerals are low-Ca pyroxene and calcic plagioclase together with accessory silica polymorph and ilmenite (associated with multiple small grains of zircon).

Some pyroxene has unexsolved pigeonite cores whereas other pyroxenes have exsolved into augite lamellae within host orthopyroxene. Geochemistry : Low-Ca pyroxene cores Fs. FeO/MnO = 29, N = 2, orthopyroxene host Fs.

FeO/MnO = 34, clinopyroxene exsolution lamellae Fs. FeO/MnO = 31-35, N = 2, plagioclase An.

An achondrite from the eucrite group; the meteorite is a monomict breccia. The highlighted words are defined as follows. Achondrite: A stony meteorite that lacks chondrules and originated on a differentiated parent body.

Eucrite: Eucrites are the most abundant type of basaltic achondrite, linked by geochemical traits such as oxygen isotopic ratios and certain elemental ratios, of which Fe/Mn is the most widely cited. The main minerals in eucrites are Fe-rich pyroxene and Na-poor plagioclase. The eucrites are strongly linked with the diogenites and howardites; the three groups are collectively known as meteorites and may come from asteroid 4 Vesta.
