Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form" The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical changeThe protolith may be a sedimentary, igneous, or existing metamorphic rock...
