Metamorphic Facies Table 25-1. The definitive mineral assemblages that characterize each facies (for mafic rocks). Table 25-1. Definitive Mineral Assemblages of Metamorphic Facies Facies Definitive Mineral Assemblage in Mafic Rocks Zeolite zeolites: especially laumontite, wairakite, analcime Prehnite-Pumpellyite prehnite + pumpellyite (+ chlorite + albite) Greenschist chlorite + albite + epidote (or zoisite) + quartz ± actinolite Amphibolite hornblende + plagioclase (oligoclase-andesine) ± garnet Granulite orthopyroxene (+ clinopyrixene + plagioclase ± garnet ± hornblende) Blueschist glaucophane + lawsonite or epidote (+albite ± chlorite) Eclogite pyrope garnet + omphacitic pyroxene (± kyanite) Contact Facies After Spear (1993) Mineral assemblages in mafic rocks of the facies of contact metamorphism do not differ substantially from that of the corresponding regional facies at higher pressure.
It is convenient to consider metamorphic facies in 4 groups: 1) Facies of high pressure blueschist and eclogite facies lower-T blueschist facies occurs in areas of low T, high P gradients, characteristic of subduction zones Eclogites indicate high P, moderate to high T gradients.
