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. 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. sharp 80 inch tv price best buy
