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 millimeters (0.2 to 0.4 in) thick. The mineral grains in a schist are typically from 0.25 to 2 millimeters (0.01 to 0.08 in) in size and so are easily seen with a 10× hand lens. Typically, over half the mineral grains in a schist sh… WebProtolith Protolith refers to the original rock, prior to metamorphism. In low grade metamorphic rocks, original textures are often preserved allowing one to determine the …

Web7.5.2.8 Amphibolites. Amphibolites are the most common metamorphic rocks formed by regional metamorphism under high pressure and high temperature (Fig. 7.5). The amphibolites usually occur along with the mica schist and gneiss. The development of schistosity is considerably less pronounced in amphibolites than those in the amphibole …
