How Slate Is Formed
Dec 17, 2020
Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. It is popular for a wide variety of uses such as roofing, flooring, and flagging because of its durability and attractive appearance.
Slate was formed under low-grade metamorphic conditions—i.e., under relatively low temperature and pressure. The original material was a fine clay.
Slate is formed by a metamorphosis of clay, shale and volcanic ash that results to a fine-grained foliated rock, resulting in unique slate.
Slate is a low grade metamorphic rock which is formed by the alteration of shale or mudstone by regional metamorphism. Slate is a fine grained foliated rock.
Slate, also called Slate, is a kind of shallow metamorphic rock, formed by clayey, sandy silty sedimentary rock or intermediate-acid tuff rock and sedimentary tuff through slight metamorphism.The SLATE is naturally well stratified, the thickness of single layer is uniform, the hardness is moderate, with corrosion resistance, acid and alkali resistance, high and low temperature resistance, pressure resistance, folding resistance, weathering resistance, sound insulation, heat dissipation and other characteristics.
