WebAt shallow depths within the crust (usually less than 6 km) the heat sources responsible for contact metamorphism are bodies of hot magma (e.g. igneous intrusions) which raise the temperature of the surrounding rocks. These thermal affects are usually restricted to the contact zones of the intrusions, hence the term contact metamorphism. WebContact metamorphism At shallow depths within the crust (usually less than 6 km) the heat sources responsible for contact metamorphism are bodies of hot magma (e.g. igneous … WebMay 6, 2024 · The main factors that control metamorphic processes are: the mineral composition of the parent rock, the temperature at which metamorphism takes place, the amount and type of pressure during metamorphism, the types of fluids (mostly water) that are present during metamorphism, and the amount of time available for metamorphism. … great ranch names

This most often occurs near igneous intrusions, where hot magma forces itself into sedimentary strata. The … WebDuring metamorphism, protolith chemistry is mildly changed by increased temperature (heat), a type of pressure called confining pressure, and/or chemically reactive fluids. Rock texture is changed by heat, confining pressure, and a type of pressure called directed stress. Temperature (Heat)
