The types of dolomite deposits in China are as follows:
table  China's dolomite deposit type
Deposit name | Mineral rock types and their occurrence | Example |
Marine dolomite deposit | The deposits are mostly produced in limestone systems. The ore bodies are layered or lenticular, and the dolomite and limestone can change along the direction and inclination. The ore is densely packed, sometimes with fluorite and lapis lazuli. These deposits are large in scale and good in quality and are the most important type of dolomite deposit. The geological grade of Wulongquan dolomite deposit: MgO 18.77%, CaO 33.52%, SiO 2 0.51% The geological grade of the dolomite bridge dolomite deposit: MgO 18.82%, CaO 33.29%, SiO 2 0.51% Geological grade of Nanjing Dolomite Mine: MgO 20.47%, CaO 30.0%, SiO 2 1.59% | Wuchang Wulongquan Limestone , Dolomite Mine, Hebei Zunhua Weijiajing Mine, Nanjing Dolomite Mine, Hunan Xiangxiang Chess Bridge Dolomite Mine |
Lagoon phase dolomite deposit | The deposit is layered or lenticular and has a small scale. The main difference from the former type is that this type of dolomite is symbiotic with gypsum or anhydrite , and is often under the gypsum or salt-bearing rock layer or interbedded layer in the layer position. The material composition is complex and the quality is poor. Industrial value of mineral deposits is rare |
