Foliated Metamorphic Rocks

Foliated approach the parallel association of certain mineral grains that gives the rock a striped appearance. Foliation paperwork while pressure squeezes the flat or elongate minerals within a rock so that they grow to be aligned. These rocks expand a platy or sheet-like structure that reflects the route that pressure become applied.

French Slate, Paleoproterozoic; Snowy Range Road roadcut, Medicine Bow Mountains, Wyoming, USA


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.


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.


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.


Gneiss is a foliated metamorphic rock ,Is a common dispensed type of rock shaped by high-grade regional metamorphic approaches from pre-current formations that have been initially both igneous or sedimentary rocks Gneiss, metamorphic rock that has a awesome banding, which is apparent in hand specimen or on a microscopic scale.


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.
