A rock rich in garnet and pyroxene that forms at extremely high pressures and moderate to high temperatures is called a(n) _____ . 3) Agents of metamorphism include heat, pressure, reactive fluids, and stress. The relative and absolute mineral proportions depend both on the special chemical composition of the parent rock and on the degree of metamorphism. Kinds of Metamorphic Rocks. The protolith (or parent rock) for phyllite is shale or pelite, or slate, which in turn came from a shale protolith. Amphibolite is a very unfortunate name given to two very different things: a rock type, and a metamorphic facies.

Serpentinite is a metamorphic rock that is mostly composed of serpentine group minerals. What are synonyms for amphibolite? Amphibolites contain large grains of black hornblende and whitish plagioclase in subequal proportions. The amphibolite facies comprises relatively high metamorphic rocks like biotite schist and amphibole schist. the homogeneity of the magmatic parent sam- (1983). bedding or schistosity of the parent rock and cut through later-formed crystals of the metamorphic rock. Amphibolite is a metamorphic rock that contains amphibole, especially hornblende and actinolite, as well as plagioclase. All styles of mineralisation are related to amphibolite sediment contacts but the distribution of scheelite is erratic. The parent rock is typically basalt. Its protolith (parent-rock) can be Basalt, Gabbro, or Ultramafic igneous rock.
