Metamorphic rock - Wikipedia

Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism.The original rock is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure of 100 megapascals (1,000 bar) or more, causing profound physical or chemical changes.During this process, the rock remains mostly in the solid state, but ...
