Greenschist, Amphibolite, Granulite Facies The transition from amphibolite to granulite facies occurs in the range 650-700 o C If aqueous fluid, associated pelitic and quartzofeldspathic rocks (including granitoids) begin to melt in this range at low to medium pressures , so that migmatites may form and the melts may become mobilized Not all pelites and quartzo-feldspathic rocks reach the granulite facies as a result Amphibolite to granulite facies 650-700 700°C; if H 2 O present, melting of pelites and quartzofeldspathic rocks may occur to form migmatites.
Transition to Granulite Facies Mafic rocks generally melt at somewhat higher temperatures If water is removed by the earlier melts the remaining mafic rocks may become depleted in water Hornblende decomposes and orthopyroxene + clinopyroxene appear This reaction occurs over a temperature interval of at least 50 o C
