Abstract
Although prevalent in some planetary crusts such as that of the Moon (and possibly Mercury), anorthosites are not abundant on Earth, except in a few places like the Grenville Province of the eastern Canadian Shield. Nevertheless, terrestrial anorthosites are distinctive, and may be classified into at least five separate types: (1) Archean megacrystic, (2) Proterozoic massif-type, (3) those in layered mafic intrusions, (4) oceanic, and (5) inclusions in other igneous rocks.
