Diatomaceous earth deposits in China are all non marine deposits, mainly freshwater lacustrine deposits. The formation and distribution of diatomite deposits in many areas are closely related to volcanic activity (basalt) since Cenozoic. More than 70 diatomaceous earth mines have been explored in 14 provinces of China, forming a tripartite situation with Jilin, Zhejiang and Yunnan. A large amount of diatomite is stored in the eastern coastal area, western Xinjiang, northern Heilongjiang, southern Guangdong, Hainan, central Inner Mongolia, Hebei, Shandong, Sichuan, etc. except that the Changbaishan mine in Jilin is of good quality, the original soil in China is of medium and low grade.

It is well known that diatomite mud developed by scientific technology is used in decoration industry. In fact, the application of diatomite is not only in decoration industry, but also in food, medical treatment, sewage treatment and agriculture.

The most widely used in agriculture is as filler for pesticides and compound fertilizers. As a soil regulator for flowers, it can regulate the moisture and air in the soil, prevent mildew root, rotten root and sun exposure death, and promote the effective growth of flowers. The advantages of using diatomite as pesticide powder filler are neutral pH value, non-toxic, good suspension performance, strong adsorption performance, light unit weight, 135% oil absorption rate, fineness of 325 mesh -500 mesh, good mixing uniformity, heat preservation in soil, loosening soil, prolonging drug effect, fertilizer effect time, improving soil, and promoting crop growth. There are many application fields not mentioned here. The benefits of diatom mud made of such excellent materials are self-evident.
