Marble is mined from stone mines and mines are spread all over the world. Like oil, there are many oil resources in the world. They are all gifts that nature has given us, and they are non-renewable resources in a short time.
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. It is mainly composed of calcite, limestone, serpentine and dolomite. Its main component is calcium carbonate, accounting for more than 50%.

3, let your friends come to our company for one week of internship, free to popularize all kinds of stone knowledge; PS: You can also ask your friends by the way, ask him if the United States is the United States? Is Jingdong Tokyo?
