WebAKA Thermal metamorphism, occurs in Earth's upper crust (low pressure), when rocks immediately surrounding a molten igneous body are "baked" (high temperature). … 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.

WebJun 14, 2024 · Foliation occurs when pressure is put on one side of the grains more than any other direction. This creates platy structured rocks, which align under pressure. Recrystallization is a process where the chemical composition a rock is changed. The mineral grains that are produced in this process are larger than the original grains. WebSep 21, 2024 · Foliation is produced in a rock by the parallel alignment of platy minerals (e.g. muscovite biotite chlorite) needle-like minerals (e.g. hornblende) or tabular minerals (e.g. feldspars).

Typically this is a type of fault, but it may be difficult to place a distinct fault plane into the shear zone. Shear zones may form zones of much more intense foliation, deformation, and folding. sevtech shoggoth lair
