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.

WebMay 10, 2024 · Gneiss ("nice") is a rock of great variety with large mineral grains arranged in wide bands. It means a type of rock texture, not a composition. This type of metamorphic was created by regional metamorphism, in which a sedimentary or igneous rock has been deeply buried and subjected to high temperatures and pressures. WebRegional metamorphism is associated with the major events of Earth dynamics, and the vast majority of metamorphic rocks are so produced.
