Anorthosite

Anorthosite (pronunciation: /ænˈɔːrθəsaɪt/) is a phaneritic, intrusive igneous rock characterized by a predominance of plagioclase feldspar (90–100%), and a minimal mafic component (0–10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present. Lunar anorthosites constitute the light-coloured areas of the Moon's surface and have been the subject of much research.
