granulite faciesOne of the major divisions of the mineral facies classification of metamorphic rocks, encompassing rocks that formed under intense temperature-pressure conditions (higher than 950°F, or 500°C). The minerals found in the rocks of granulite facies include hornblende, pyroxene, biotite, garnet, calcium plagioclase, and quartz or olivine. See also amphibolite facies. granulite facies [′gran·yə‚līt ′fā·shēz] (petrology) A group of gneissic rocks characterized by a granoblastic fabric and formed by regional dynamothermal metamorphism at temperatures above 650°C and pressures of 3000-12,000 bars. Granulite Facies metamorphic rocks that formed as a result of regional metamorphism at great depths in almost anhydrous conditions. Granulite facies are represented by quartzose-feldspathic gneisses with garnets or pyroxene. Want to thank TFD for its existence?
