WebPhyllite is a type of foliated metamorphic rock created from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation. It is primarily composed of quartz, sericite mica, and chlorite. Phyllite has fine-grained mica flakes in a preferred orientation, whereas slate has extremely fine clay flakes that … WebPhyllite’s composition is quartz, muscovite and chlorite: essentially it’s slate that has been subjected to a longer period of metamorphosis. Slate was formed as a result of fine-grained, shale-type sediments being deposited deep on the ocean floor, the thick beds slowly compressing to form a layered sedimentary rock.
