How is slate formed? Step by step

                                                  Slate Formed

Slate is formed by a metamorphosis of clay, shale and volcanic ash that results to a fine-grained foliated rock, resulting in unique slate textures. It is a metamorphic rock, being the finest grained foliated of its kind. It is composed mainly of the minerals quartz and muscovite or illite, often along with biotite, chlorite, hematite and pyrite and less frequently, graphite, kaolinite, magnetite, tourmaline, or zircon as well as feldspar.
