Fault-Affected Fluid Circulation Revealed by Hydrochemistry and Isotopes in a Large-Scale Utilized Geothermal Reservoir
Figure 6
Isotopes of cold groundwater and geothermal groundwater at Xiongxian. The dashed lines are the possible processes: red line indicates the oxygen shift due to water-rock interaction (WRI); the dashed blue line shows the hydrogen shift due to inferred bacterial sulphate reduction (BSR); and the dashed black line is the mixing line.
