Amphibolite, a rock composed in large part or dominantly of minerals of the amphibole institution. The term has been implemented to rocks of both igneous or metamorphic foundation. In igneous rocks, the term hornblendite is greater not unusual and restrictive; hornblende is the maximum not unusual amphibole and is traditional of such rocks.

Phyllite is a foliated metamorphic rock that has been low pressure and heat. Phyllite formation from slate that is further metamorphosed so that very fine grained mica mineral achives. It composed of mainly flake-shaped mica minerals. This mica minerals is strong parallel alignment, so easly to split into sheets or slabs. Also alignment of mica grains gives a reflective sheen on phyllite. Generally Phyllite is gray, black or greenish color and frequently weathers out of a tan or brown.

Schist is medium grade metamorphic rock, formed by means of the metamorphosis of mudstone / shale, or some forms of igneous rock, to a higher diploma than slate, i.E. It has been subjected to better temperatures and pressures.

Pinolith is a unique and visually striking metamorphic rock that is primarily composed of two distinct minerals: white magnesite and black graphite. It is...

Slate is a fine-grained, foliated metamorphic rock this is created via the alteration of shale or mudstone by means of low-grade local metamorphism. It is famous for a extensive form of makes use of such as roofing, floors, and flagging due to its sturdiness and appealing look.
