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. WebAug 16, 2016 · Dynamic metamorphism is the process where rocks along the fault zones are altered due to high pressure. The rocks that are formed with this type of metamorphism are called mylonites. Mylonites are compact, fine-grained rocks with thin laminations or layers. Regional metamorphism is the most common form of metamorphism that …

WebThere are three ways that metamorphic rocks can form. The three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing body of rock. When this happens the existing rocks temperature rises and also becomes infiltrated with fluid from the magma.

WebWhile rocks can be metamorphosed at depth in most areas, the potential for metamorphism is greatest in the roots of mountain ranges where there is a strong likelihood for burial of relatively young sedimentary rock to great depths, as depicted in Figure 7.3.2.
