Schist
Medium- to coarse-grained, mica-bearing metamorphic rock with well-developed foliation (layered structure) termed schistosity. Schist is derived primarily from fine-grained, mica-bearing rocks such as shales and slates. The schistosity is formed by rotation, recrystallization, and new growth of mica; it is deformational in origin. The planar to wavy foliation is defined by the strong preferred orientation of platy minerals, primarily muscovite, biotite, and chlorite. The relatively large grain size of these minerals (up to centimeters) produces the characteristic strong reflection when light shines on the rock.

What is the location of schist?
Schist is a form of metamorphic rock in which a sedimentary rock has been subjected to heat and pressure. These change agents will alter the structure of the rock, and will allow / cause the minerals in the rock to change and aggregate. Schist is a very common rock type, but does need the parent rock to have undergone metamorphism.

Gneiss is formed from what rock?
Gneiss is a metamorphic rock. It is formed form another metamorphic rock called schist (sh-ist). Schist is formed form fine grained sedimentary rock (often shale). While gneiss is formed by great pressure from moving plates of the earth's crust.
