mylonite
Quick Summary
Mylonites are a type of rock formed by dynamic metamorphism, specifically through extreme cataclastic deformation. This process occurs along fault planes or in zones of intense shearing, where the rock's texture is altered by ductile shearing or mechanical shattering of grains. Mylonites are characterized by their extremely fine-grained nature, often appearing laminated with layers formed from deformed material. While they may show slight development of new minerals, their texture is primarily a result of the physical deformation of the original rock.12

- cataclastite
Mylonites are the products of extreme cataclastic deformation. They are extremely fine-grained, but mineral fragments of the parent rock can be seen under the microscope. Most mylonites are laminated, the layers formed by different grain sizes of deformed material.
