8 Metamorphic Minerals and Metamorphic Rocks
The Causes of MetamorphismPressure and TemperatureMetamorphic TexturesMetamorphic ReactionsMetasedimentary Rocks and Mineralsmetaigneous Rocks and MineralsHigh-Pressure Rocks and MineralsMetamorphic rocks, and the processes that create them, are key parts of the rock cycle that also includes igneous and sedimentary rocks and processes. Most metamorphic rocks form when heat, pressure, or chemically reactive fluids cause changes in preexisting rocks. The preexisting, or parent rocks, are called protoliths. Protoliths can be igneous, sedimentary, or metamorphic rock of all sorts. The changes that occur during metamorphism may involve changes in rock texture,
