How do geologists classify metamorphic rocks
WebMetamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet. The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact ...
