ISOTOPIC HYDROGEOCHEMISTRY OF MID-LOW TEMPERATURE GEOTHERMAL WATER IN JIANGXI PROVINCE
Sun Zhanxue Li Xueli Shi Weijun (Department of Hydrogeology)
The stable isotopes of oxygen and hydrogen of mid-low geothermal water in Jiangxi province indicates that geothermal water in the region are of meteoric origin. Other isotoplc compositions, such as tritium, carbon-14, radium and redon, reveals the age of the geothermal water, Mixture between geothermal water and shallow cold water in the area is discussed by combining the hydrogeo chemical methods with isotopic methods in the paper. The variation law of isotopic composition of geothermal water and cold groundwater has been systematically studied.
