Schistosity is a platy structure that forms during metamorphism as a result of the parallel, even and continuous alignment of platy and columnar mineral constituents on the same plane. Common platy and columnar minerals are mica, hornblende, talc and chlorite. Schistosity is common in moderately metamorphosed rocks. The mineral grains of schistosity are coarser than those of phyllitic foliation, and they are identifiable to the naked eye.
