Biotite schist protolith
Did you know?
WebPelitic protoliths are mainly composed of clay minerals derived from weathered and eroded continental crust. With increasing metamorphic grade, they are transformed to slates, phyllites, mica-schists, and granulites. Carbonate rocks mainly originate from biogenic sediments. Pure carbonate sediments are SiO2-free. WebThis schist contains large quantities of muscovite indicating that it had a pelitic protolith. This pelite was subjected to high pressures and temperatures during regional metamorphism, resulting in the …
Web7.5.2.8 Amphibolites. Amphibolites are the most common metamorphic rocks formed by regional metamorphism under high pressure and high temperature (Fig. 7.5). The amphibolites usually occur along with the mica schist and gneiss. The development of schistosity is considerably less pronounced in amphibolites than those in the amphibole …
