Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. See more Schist is a medium-grained metamorphic rock showing pronounced schistosity. 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 … See more Geologists define schist as medium-grained metamorphic rock that shows well-developed schistosity. Schistosity is a thin layering of the rock produced by metamorphism (a foliation) that permits the rock to easily be split into flakes or slabs less than 5 to 10 … See more In geotechnical engineering a schistosity plane often forms a discontinuity that may have a large influence on the mechanical behavior (strength, deformation, etc.) of rock masses in, for example, tunnel, foundation, or slope construction. A hazard may exist even in … See more • Samuels, Andrea (November 2008). "An Examination of Mica Schist". Micscape magazine. Photographs of Manhattan schist. • "Geologic units containing Schist". U.S. Geological Survey. See more The word schist is derived ultimately from the Greek word σχίζειν (schízein), meaning "to split", which refers to the ease with which schists can be split along the plane in which the platy minerals lie. See more Schistosity is developed at elevated temperature when the rock is more strongly compressed in one direction than in other directions (nonhydrostatic stress).
