WebDynamic metamorphism When directed pressure or stress is the dominant agent of metamorphism, it is termed dynamic; other terms are dislocation, kinematic, and mechanical metamorphism. Mineralogical changes … WebDynamic metamorphism is the result of very high shear stress, such as occurs along fault zones. Dynamic metamorphism occurs at relatively low temperatures compared to …
WebMetamorphic petrologists studying contact metamorphism early in the 20th century introduced the idea of metamorphic facies (part of a rock or group of rocks that differs from the whole formation) to correlate metamorphic events. The concept was first defined in 1914 by a Finnish petrologist, Pentti Eelis Eskola, as any rock of a metamorphic formation that … WebQ1) The term metamorphism refers to changes in a rocks mineralogy, texture, and/or composition that occur predominantly in the solid state under conditions between those …
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. ...
