Slate(Metamorphic) ~ -low-grade metamorphism -fine gained - originally mudrocks, and volcanic ash Phyllite (Metamorphic) ~ -glassy sheen an wavy texture -more temp and pressure than slate -Composed mainly of fine crystals of muscovite and chlorite Schist(Metamorphic) ~ -Medium to coarse grained -schist describes its texture(strongly foliated aka schistosity) More temp and pressure than phyllite Gneiss(Metamorphic) ~ -Medium to coarse-grained -High-grade metamorphism(very high temp ...
