Foliated metamorphic rocks exhibit a layering affect with parallel layers of mineral crystals one on top of the other. A good example of this is gneiss, which has alternating layers of light and dark minerals. Foliation takes place when pressure is applied to crystals and they recrystallize or align themselves at right angles to the direction of the applied directional stress.

What is metamorphic rock in which mineral crystals are arranged in parallel layers or band?

The metamorphic rock you are referring to is called foliated rock. Foliated rocks have mineral crystals aligned in parallel layers or bands, resulting from the re-alignment of minerals due to pressure and heat during metamorphism. Examples of foliated rocks include slate, schist, and gneiss.

Do non-foliated metamorphic rocks contain bands of crystals?

All rocks except volcanic or tectonic glasses have crystals. Therefore all metamorphic rocks have crystals, however in lower metamorphic environments these crystals may remain microscopically small.


What is a description of foliated metamorphic rock?

Foliated means the crystals are formed in parallel bands. This is formed when pressure crushes the rock so that it becomes denser. This causes the crystals to produce band as space runs out at 900 to the pressure. E.g. Weight of rocks above produce bands horizontally.
