The Mile-Shizong Fault Zone in Eastern Yunnan is rich in geothermal resources. However, due to the less research and unclear genetic mechanism, the sustainable development and utilization of geothermal resources in the region has been restricted. Taking the hot spring water and geothermal well water in Laochang area in the north section of the Mile-Shizong Fault Zone as the research object, this paper comprehensively applies the integration of field investigation, hydrogeochemistry and environmental isotope to study the characteristics and genetic mechanism of geothermal water in the study area. The pH values of the geothermal water are between 7.30~8.12 and TDS values are between 224~382 mg/L, which belongs to weakly alkaline fresh water. The hydrochemical types of geothermal water are HCO3·SO4-Ca type and HCO3·SO4-Ca·Na type. The geothermal water contains high contents of trace components such as Fe, As and Sb, and thus are not suitable for drinking. The δ13C value of HCO3− is between −3.31‰ and −7.79‰, and the calculated δ13C value of CO2 involved in water-rock reaction is between −9.50‰ and −15.68‰, which is mainly from sedimentary organic matter. Ion ratio analysis and sulfur isotope characteristics show that the dissolution of carbonate minerals and gypsum is the main factor controlling ion concentrations of geothermal water. In addition, the oxidation and cation exchange of sulfide ore bodies in the fault zone have a certain impact on the composition of geothermal water. Hydrogen and oxygen isotope characteristic and 14C dating results show that the recharge origin of the geothermal water is the atmospheric precipitation with low temperature in the late Pleistocene, and the supply elevation is between
