Extended data:

Marble is a metamorphic rock formed by the action of high temperature and high pressure in the crust, and the internal force of the crust promotes the qualitative change of various protoliths. Qualitative change refers to the change of the structure, structure and mineral composition of the original rock, and the new rock type formed by qualitative change is called metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine and dolomite, and the main component is calcium carbonate, accounting for more than 50%. Others include magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide.

Marble is mainly used for processing into various profiles and plates, which are used as walls, floors, platforms and columns of buildings, and also as materials for memorial buildings such as monuments, towers and statues. Marble can also be carved into handicrafts, stationery, lamps, utensils and other practical works of art, which are soft, beautiful, solemn and elegant.
