Grain size of schist
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… WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer. Question: Part B 1.
