WebDynamic metamorphism. This is metamorphism produced by directed pressure and is restricted to fault zones. A good example is from the San Andreas fault zone in California. A typical rock type produced by dynamic metamorphism is a fine-grained, banded rock termed a mylonite. In these rocks the crystal size has been reduced by the deformation. WebWhat is the best definition of metamorphism? The process by which rocks are altered in composition, texture, or internal structure by extreme heat, pressure, and the introduction of new chemical substances. noun. 2. (geology) The process by which rocks are changed into other forms by the application of heat and/or pressure. noun.
