Barite deposits in carbonate rock area forms under shallow condition with karst hydrothermal brine solution as medium and karstification as leading factor of mineralization.
The karst surface collapse in Wuhan happened at the intersection between the ne first terrace binary-structured deposits of Yangtze River and carbonate in the core of E-W syncline.
