"Foliation is usually formed by the preferred orientation of minerals within a rock. Usually, this is the result of some physical force and its effect on the growth of minerals. The planar fabric of a foliation typically forms at right angles to the maximum principal stress direction. In sheared zones, however, planar fabric within a rock may not be directly perpendicular to the principal stress direction due to rotation, mass transport, and shortening. " - Foliation occurs when

WebOct 7, 2024 · Penetrative foliation is caused by the alignment of minerals within the rock, while non-penetrative foliation is caused by the alignment of minerals on the surface of the rock. There are many different types of flaws in rocks. Mineral reorientation occurs when minerals are subjected to high pressure and temperature. WebThe layering within metamorphic rocks is called foliation, and the rock is known as foliated or banded rock. The term "foliation" is derived from the Latin word folia, which means "leaves.". Foliation occurs when a strong compressive force is applied to a recrystallizing rock from one direction.
