Most metamorphic rocks are the result of regional metamorphism (also called dynamothermal metamorphism). These rocks were typically exposed to tectonic forces and associated high pressures and temperatures.

How Are Metamorphic Rocks Formed? (Full Explanation) - Outforia

WebVarious forms of metamorphism exist, including regional, contact, hydrothermal, shock, and dynamic metamorphism. These differ in the characteristic temperatures, pressures, and rate at which they take place and in the extent to which reactive fluids are involved. WebContact Metamorphism (often called thermal metamorphism) happens when rock is heated up by an intrusion of hot magma. In this photo, the dark grey rock is an intrusion (a sill) between layers of a paler grey limestone. Just above and below the intrusion, the limestone has been altered to form white marble. birmingham i20 59 bridge replacement

WebRegional metamorphism is associated with the major events of Earth dynamics, and the vast majority of metamorphic rocks are so produced. They are the rocks involved in the cyclic processes of erosion, sedimentation, burial, metamorphism, and mountain building ( orogeny ), events that are all related to major convective processes in Earth’s mantle. WebThere are two general types of metamorphism: regional and contact metamorphism. Regional metamorphism occurs over a large area that is hundreds to thousands of square miles. These rocks are deeply buried in the crust where they are subjected to high pressures and temperatures.
