Hydrochemical Characteristics and Evolution of Geothermal Fluids in the Chabu High-Temperature Geothermal System, Southern Tibet

Table 3

Calculation results of geothermal reservoir temperatures in the research area ( in °C, except for mass flow rate in L/min). The results in bold font are the optimum temperatures selected from the quartz geothermometers taking into account the measured emerging temperatures and the mass flow rates of the spring samples.
