Metamorphic rock process
WebTo name a metamorphic rock, the mineralogy is listed (in decreasing order of abundance) and then the rock is given a suffix relating to its general texture. For example: A rock composed of 60% muscovite and 40% biotite, both occurring as interlocking platy grains - a schistose (schist-like; schists are a group of medium-grade metamorphic rocks) texture … WebMetamorphism is the process that changes existing rocks (called protoliths) into new rocks with new minerals and new textures. Increases in temperature and pressure are …
