Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression.

WebFoliation is any planar arrangement of mineral grains or structural features within the metamorphic rock. This can be produced by rotation of platy/or elongated minerals, recrystallization of minerals, and changing the shape of equidimensional grains into elongated shapes that are aligned. WebSlate is considered as the finest grained foliated metamorphic rock. Metamorphic rocks are formed from the change in form of existing rocks, a process called metamorphism. Slate arises from the repetitive layering …

Slate is composed mainly of clay minerals or micas, depending upon the degree of metamorphism to which it has been subjected.
