Slate fine grained clayey metamorphic rock that cleaves or splits readily into thin slabs having great tensile strength and durability. Slate is a metamorphic rock with a dull luster.
Slate rock is an example of a sedimentary rock.
Is slate a rock. The most common color of slate is gray but it can also be brown green purple or blue. Slate is a fine grained foliated homogeneous metamorphic rock derived from an original shale type sedimentary rock composed of clay or volcanic ash through low grade regional metamorphism. True slates do not as a rule.
Some other rocks that occur in thin beds are improperly called slate because they can be used for roofing and similar purposes. Clay minerals in the parent rock metamorphose into mica minerals biotote chlorite muscovite which are aligned along foliation planes perpendicular to the direction of pressure. Slate is a fine grained foliated metamorphic rock that is created by the alteration of shale or mudstone by low grade regional metamorphism.
Slate is formed when a sedimentary rock shale mudstone or basalt is compressed. It is popular for a wide variety of uses such as roofing flooring and flagging because of its durability and attractive appearance. It is the finest grained foliated metamorphic rock.
Foliation may not correspond to the original sedimentary layering. Over time slate may transition into other metamorphic rocks such as phyllite or schist. It gets formed from either clay or volcanic ash that has been superheated and pressurized underground.
Slate is a low grade metamorphic rock generally formed by the metamorphosis of mudstone shale or sometimes basalt under relatively low pressure and temperature conditions.
