Phyllite
A variety of Metamorphic
What is Phyllite?
Phyllite is a common metamorphic rock derived from slate. Being very soft, this rock has few industrial uses; however, because it often possesses a handsome sheen (due to tiny flakes of mica) and is easy to cut, it is occasionally used for decorative garden stones, flagstones, or tiles.
Uses & Applications
Due to its sheen, phyllite is used for some of the more decorative construction purposes. Phyllite can commonly be seen in home interiors as countertops or flooring, though it may also be used outdoors as paving stones or sidewalks. You may see this rock in cemeteries as it is commonly used to create tombstones. It has also been known to be used to create writing slates.
