GENERAL GEOLOGY

Detailed explanation-1: -Dynamic metamorphism is the result of very high shear stress, such as occurs along fault zones. Dynamic metamorphism occurs at relatively low temperatures compared to other types of metamorphism, and consists predominantly of the physical changes that happen to a rock experiencing shear stress.

Detailed explanation-2: -Dynamic metamorphism takes place anywhere that faulting occurs at depth in the crust. Thus, mylonites can be found at all plate boundaries, in rifts, and in collision zones.

Detailed explanation-3: -Dynamic metamorphic rocks are restricted to narrow zones adjacent to faults or thrusts. The high shear stresses associated with faults and thrusts crush the adjacent rocks. The rise in temperature is produced by frictional heat generated within the fault zone.

Detailed explanation-4: -Cataclastic metamorphism occurs as a result of mechanical deformation, like when two bodies of rock slide past one another along a fault zone. Heat is generated by the friction of sliding along such a shear zone, and the rocks tend to be mechanically deformed, being crushed and pulverized, due to the shearing.

Detailed explanation-5: -Metamorphic rocks formed when rocks are buried to depths with high temperature and pressure are found where rocks are squeezed and crumpled into mountains—that is, at convergent plate boundaries. The hot fluids mostly form when water flows near magma.
