ABSTRACT: Based on comparative analysis on hydrochemical characteristics of geothermal water in the north part of Liaokao fault, this research focuses on studying the indicative significance of hydrochemical characteristics for the formation of geothermal water. The result shows that: (1) There is no obvious hydraulic connection between the karst geothermal water (occurred in the east part of the Liaokao fault) and the sandstone geothermal water (occurred in the west part of Liaokao fault). (2) In a close hydrological environment, caused by tectonic activities, geothermal water remains longer time in reservoir, hence the water-rock interaction is more complete, with high degree of concentrations, whereas the renewable capacity of the water is weaker. (3) There is no high temperature mantle source fluid mixed in the geothermal water. Karst geothermal water occurred deep circulatory convection along Liaokao fault and its secondary fault, therefore there is deep crust source fluid added into the geothermal water, closer to the Liaokao fault, the greater affected by the deep crust fluid. However, sandstone geothermal water has weak deep circulatory convection. |
