A new classification of barite deposits is proposed based on a study of the distribution, ore types, geological characteristics, ore-forming material sources, ore-forming temperatures, and metallogenic models of barite deposits in China. The deposits are divided into five types, sedimentary, hydrothermal, stratabound hydrothermal vein, volcano-sedimentary, and weathering (eluvium–talus) types, with each having a distinct mineralization model. These deposits formed in continental-rift, back-arc-basin, and intracontinental-uplift tectonic environments. Barite ore bodies are stratabound or veined and are most common in Cambrian, Devonian, and Mesozoic host rocks. Most barite deposits were formed at medium to low temperatures (100–300 °C). Mineralization models for the different types of barite deposit are presented in detail.
