Schist

Schist (pronounced / ʃ ɪ s t / SHIST) is a medium-grade metamorphic rock formed from mudstone or shale. Schist has medium to large, flat, sheet-like grains in a preferred orientation (nearby grains are roughly parallel). It is defined by having more than 50% platy and elongated minerals (such as micas or talc), often finely interleaved with quartz and feldspar.

The recrystallization forms many larger crystals in particular to mica (muscovite and biotite), quartz, feldspar, garnet, staurolite, and sillimanite, and is well-observed macroscopically. In addition to sericite, the mica schist contains quartz, acid plagioclase, chlorite, and typical metamorphic minerals, such as graphite, garnets, kyanite, andalusite, and staurolite.

Schist | Encyclopedia

 · Schist Schist is a metamorphic rock consisting of mineral grains that are more or less aligned in layers. Because of this structure, schist tends to cleave into flakes or slabs.
