Schistosity is the texture that results from the alignment of abundant, coarse-grained, mica flakes in a medium-grade regional metamorphic rock. This texture is characterized by the parallel or subparallel alignment of platy minerals like mica, which gives the rock a foliated appearance and allows it to be easily split along the mica-rich layers.
