Pyroxenite is a plutonic rock that consists of dark minerals in the pyroxene group plus a little olivine or amphibole minerals. Pyroxenite belongs to the ultramafic group, meaning that it consists almost entirely of dark minerals rich in iron and magnesium. Specifically, its silicate minerals are mostly pyroxenes rather than the other mafic minerals, olivine and amphibole. In the field, pyroxene crystals display a stubby shape and square cross-section whereas amphiboles have a lozenge-shaped cross-section.

Moon rocks contain pyroxenite and a magnet will adhere to pyroxenite due to ts high conentration of magnetite.
