|Marble is a metamorphic rock formed by the high temperature and high pressure of the original rock in the earth's crust. The internal force of the earth's crust promotes the process of qualitative change of various types of rock. The qualitative change refers to the change of the structure, structure and mineral composition of the original rock. The new type of rock formed by the qualitative change is called metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine and dolomite. Its main component is calcium carbonate, accounting for more than 50%. Others include magnesium carbonate, calcium oxide, manganese oxide, and silicon dioxide.|
Marble is generally soft in physical properties, which is relative to granite. In interior decoration, marble countertops, window sills, indoor floors, etc. are suitable for use in marble. Marble is the trade name, not a petrological definition. Marble is a major category of natural architectural decorative stone. It is generally referred to as a metamorphic or undeformed carbonate rock with decorative functions that can be processed into building stone or crafts. It is named after the stone with beautiful color and pattern produced by Dang Cangshan, Dali City, Yunnan Province, China. Marble refers to marble, limestone, dolomite, and skarn and marble formed by different alterations of carbonate rocks.
