Many different styles of metamorphic facies are recognized, tied to different geologic and tectonic processes.Schist. Schist is a strongly foliated medium-grade metamorphic rock. It is characterized by an abundance of platy or elongated minerals (micas, chlorite, talc, graphite, amphiboles) in a preferred orientation. Varieties of this rock type share similarities in appearance (schistosity) but may be highly variable in composition.Serpentinite is a rock composed predominantly of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake.

Gneiss, on the other hand, is formed in the pattern of layers of sheet-like planar structures. Schist and Gneiss are two different types of rocks that look remarkably like. The reason for this is because they are both types of metamorphic rock. Schist is a type of metamorphic rock characterized by its foliated texture, which means it possesses distinct layers or bands of minerals that have undergone significant physical and chemical changes due to heat, pressure, and other geological processes.
