Gas isotopes and geochemistry of hot springs in Hengjing, Jiangxi Province

摘要

With emphasis on gas isotopes an geochemistry as well as hydrogeochemistry, a field investigation has been carried out in Hengjing geothermal area, south jiangxi province of south-eastern China. The water chemistry of the geothermal waters indicates their local meteoric water origin, whereas their gas composition and carbon and helium isotopes reveal that some gases in the geothermal waters have mantle origin
