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. WebSep 10, 2024 · As with shock metamorphism, fault zone metamorphism is a type of dynamic metamorphism. Shallow faults (close to the earth’s surface) may grind the nearby rocks into smaller, angular fragments called fault breccia, or you may see a fine clay powder called fault gouge; fault gouge forms by the chemical alteration of fault breccia. ... citibank bonus checking offer

The grey and white crystals are quartz and (limited) feldspar. 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.
