WitrynaThe metamorphic facies produced by contact metamorphism in order of increasing grade are as follows: Albite epidote hornfels; Hornblende hornfels; Pyroxene hornfels; Sanidinite; Dynamic metamorphism. Dynamic metamorphic rocks are restricted to narrow zones adjacent to faults or thrusts. The high shear stresses associated with … WitrynaContact metamorphism is restricted to the thermal halo (aureole) surrounding a pluton, batholith, or other intrusive magma body (Fig. 7.14). The effects of metamorphism are limited to a specific volume of wall rock around the magma body; the metamorphic episode is over once the magma body is cooled and crystallized.
