Foliated during contact metamorphism
WebThere are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure at all. Web2) Contact metamorphism occurs due to high temperature and interaction with fluids at relatively low pressures. This can occur next to cooling magma bodies. The major processes contributing to contact metamorphism are baking and differential melting. 3) Burial metamorphism results from burial of a sedimentary basin with sufficient fluids at

Because contact metamorphism is not caused by changes in pressure or by differential stress, contact metamorphic rocks do not become foliated.

In the ultramylonite matrix, consisting of quartz, plagioclase, muscovite and biotite, microstructures show grain growth of quartz within quartz ribbons, …
WebFeb 19, 2024 · Typically, contact metamorphism occurs at shallower levels of the crust, where the pressure is relatively low. At those shallow depths, the stresses characteristic of orogenic belts are generally small or absent thus producing metamorphic rocks that lack foliation. Contact metamorphism commonly produces fine-grained rocks.
