Schist - Wikipedia
Schist (/ ˈʃɪst / SHIST) is a medium-grained metamorphic rock showing pronounced schistosity (named for the rock). This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates.

Schist is a foliated metamorphic rock made up of plate-shaped mineral grains that are large enough to see with an unaided eye. It usually forms on a continental side of a convergent plate boundary where sedimentary rocks, such as shales and mudstones, have been subjected to compressive forces, heat, and chemical activity.

Schist - Metamorphic rocks - Sandatlas
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.
Schist: Formation, Uses and Types of Schist – Geology In
Schist is a type of metamorphic rock known for its distinctive layered or banded appearance. This characteristic, called foliation. This foliation is caused by the alignment of platy minerals, such as mica, chlorite, and talc, being flattened and aligned due to …
Schistosity | geology | Britannica
Schistosity, mode of foliation that occurs in certain metamorphic rocks as a consequence of the parallel alignment of platy and lath-shaped mineral constituents. It reflects a considerable intensity of metamorphism—i.e., changes resulting from high temperatures, pressures, and.
Schist - Geology is the Way
Schist is a low- to medium-grade metamorphic rock with a well-defined foliation and containing minerals that are visible with the unaided eye. The name derives from the Greek schizo, ‘to tear’, in reference to its very strong fissility.
