Schists are metamorphic rocks with parallel alignment of minerals.
A foiliated metamorphic rock is a metamorphic rock that has a texture of parallel alignment of mineral grains. Your Welcome...
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.

The texture of a rock with aligning parallel platy grains is said to exhibit metamorphic foliation.

Schists are metamorphic rocks with parallel alignment of minerals.
Heat is one condition that is required to form parallel alignment of minerals sometimes found in a metamorphic rock. The other condition is pressure.

A folliated texture metamorphic rock, like shist.
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.
The main characteristic of gneiss is gneissic texture, foliations (banding) caused by the parallel alignment of constituent minerals as a result of heat and pressure.
The change is in the alignment of the clay minerals and parallel alignment of micaceous minerals, from the stress of compressional forces. The water content of the shale is reduced, increasing the rock's specific gravity, and the alignment of the minerals results in a slaty cleavage.
It is a medium-grade metamorphic rock with a preponderance of the platy mineral graphite.
