Granulites are a class of high-grade metamorphic rocks of the granulite facies that have experienced high-temperature and moderate-pressure metamorphism...

Survey strongly discourages the use of granulite as a classification for rock metamorphosed to the granulite facies. Instead, such rock will often be...

The Lapland Granulite Belt is an elongate and arcuate zone of granulite rock in the Cap of the North spanning areas within Norway, Finland and Murmansk...

calcite + diopside ± forsterite (higher pressure and temperature) The granulite facies is the highest grade of metamorphism at medium pressure. The depth...

the resulting fractionated granulite rises steeply in the crust, water exits from its supercriticality phase, the granulite starts to crystallize, becomes...

as granulites in the lower continental crust at high thermal gradients. This leads to significant extraction of hydrous felsic melts from granulite-facies...

sometimes describe the leucogranite of the Mont as "granulite", but this granitic meaning of granulite is now obsolete. The mount has a circumference of...
