What Are the Three (3)types of Metamorphism? Where and Under

Question

Examlex · Accepted Answer

The Answer is Contact metamorphism takes place when a body of magma alters the surrounding country rock. At shallow depths, intruding magma raises the temperature of the surrounding rock, causing thermal alteration. Furthermore, the release of hot fluids into the country rock by the cooling intrusion can aid in the formation of new minerals. Dynamic metamorphism is associated with faults or fault zones, where rocks are subjected to high levels of differential pressure. The metamorphic rocks that result from pure dynamic metamorphism are typically restricted to narrow zones adjacent to faults. Regional metamorphism is responsible for the formation of most metamorphic rocks. It occurs over a large area and is usually caused by tremendous temperatures, pressures, and deformations all occurring together within the deeper portions of the crust. Regional metamorphism is most obvious along convergent plate boundaries where rocks are intensely deformed and recrystallized during convergence and subduction.
