There are jade mines in various countries in the world, and Russia, South Korea, Canada, New Zealand and other countries all have large jade mines. China's Xinjiang Hetian is an important producing area of ​​Hetian jade stone mine, and it is also named after Hetian origin. In addition to being distributed in mountainous areas, jade mines are also distributed in rivers. People call this jade mine an exogenous deposit, which can be divided into three categories according to its genesis. First, the slope type, this jade mine is disintegrated under weathering and then transported into the river to form. 2. The type of flooding refers to the erosion and transportation of the primary ore by the river, and it is deposited in the riverbed, and the location of the sediment can be divided into mountain water and seed material. The mountain water is formed in the upper and middle reaches of the river. Under the immersion of the river water, the desired jade will have a certain angularity, and the handling distance is relatively close. Seed jade is formed in the lower reaches of the river and is affected by the river water all the year round. Therefore, it is mostly cobblestone-shaped and angular, and this seed jade is very precious. Third, the hail type, this jade deposit is formed by glacier erosion.
