Metamorphic foliation is a preferred orientation of mineral grains within a metamorphic rock caused by pressure during metamorphism. This alignment creates a parallel arrangement of minerals, giving the rock a layered or banded appearance. Foliation helps geologists understand the history and deformation conditions of rocks during metamorphism.
Directional pressure and differential stress are necessary for foliation to form in a metamorphic rock. Directional pressure causes minerals to align in the direction of the applied pressure, while differential stress leads to the segregation and elongation of mineral grains, resulting in the development of a foliated texture.
The parallel alignment of minerals due to stress is called foliation. Foliation results from the deformation of minerals under pressure, causing them to align in the same direction. This alignment gives the rock a layered or banded appearance.
Foliation is the arrangement of minerals in a rock that results in a layered or banded appearance. It is commonly formed in metamorphic rocks through processes like pressure and temperature causing mineral alignment. Foliation is a key characteristic used to classify and identify different types of metamorphic rocks.
This arrangement is known as foliation, commonly seen in metamorphic rocks where minerals align in layers due to pressure and temperature changes during their formation.
Foliation in rocks refers to the process being split into thin sheets. It is caused by intense pressure that shapes rocks to align in particular directions.
The foliation in metamorphic minerals is always perpendicular to the direction of pressure. E.g. Vertical pressure is applied, the foliation will be horizontal, and vice-versa, the pressure is horizontal you get vertical foliation. From yahoo answers
The foliation is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.
Foliation in metamorphic rocks is produced by the alignment of mineral grains in response to directed pressure during metamorphism. Pressure causes the minerals to recrystallize and align parallel to each other, creating a banded or layered texture in the rock. This alignment results in the development of distinct planes of weakness that we observe as foliation.

Foliation is created when pressure pushes different parts of the rock in different directions.
The alignment of minerals into bands (foliation) is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.

Heat, along with applied pressures, either from depth of burial or from tectonic forces on rock.
