Granulite (Latin granulum, "a little grain") is a name used by petrographers to designate two distinct classes of rocks. According to the terminology of the French school it signifies a granite in which both kinds of mica (muscovite and biotite) occur, and corresponds to the German Granit, or to the English muscovite biotite granite.

Granulite facies, one of the major divisions of the mineral facies classification of metamorphic rocks, the rocks of which formed under the most intense temperature-pressure conditions usually found in regional metamorphism. At the upper limit of the facies, migmatite formation may occur.

Granulite refers to a type of high-grade metamorphic rock that forms under high temperature and moderate pressure. It is characterized by a granoblastic texture and contains a significant amount of quartz, feldspar or pyroxene, and garnets.

2000年11月30日 · The granulite is one of the most important rocks in the earth. Its formation was controlled mainly by the condition of terrestrial heat. Their main formation models are related to continental collision, continental extension and continental arc. In some extent, granulite is the synonym of the lower continental crust.
