The protolith subjected to metamorphism
WebbMetamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of 150 to 200 °C (300 to 400 °F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation.

Webb8 juni 2024 · Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma intrudes into or lava flows over pre-existing protolith. This combination of high temperature and low pressure produces numerous metamorphic facies. Webb10.0.0.1 Metamorphism Occurs Between Diagenesis And Melting. Metamorphism is the change that takes place within a body of rock as a result of it being subjected to high pressure and/or high temperature. The parent rock or protolith is the rock that exists before metamorphism starts. New metamorphic rocks can form from old ones as pressure and …

For simplicity, magmatic …
WebbThe type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith. During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration …
WebbTime: the longer a rock is subjected to heat and pressure, the greater the degree of metamorphism. Fluids: water and other fluids can facilitate chemical reactions and …
WebbMetamorphism is driven by heat and pressure. High heat can cause rock minerals to recrystallize in the process of metamorphism. Rocks that are buried deep in Earth are subjected to equal pressure from all directions. This confining pressure can cause a phase chang e but does not fold rocks.
