WebThe high temperatures and mineral-rich fluids from the magma can alter the composition and texture of the surrounding rocks, causing them to metamorphose. In addition to these processes, metamorphic rocks can also form through hydrothermal metamorphism, which occurs when hot mineral-rich fluids circulate through rocks and cause them to change.

WebMetamorphism 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.
