Geochemistry of Tattapani thermal springs, madhya Pradesh, India—field and experimental investigations Original Research Article

The chemical composition of Tattapani thermal springs, together with the experimental results on host rock-meteoric water interaction at 100°C, indicate dissolution of K-feldspars and albite during the initial stages of reaction. These phases control the chemical composition of the thermal springs. The estimated reservoir temperatures range from 205 to 217°C. Assuming an average thermal gradient of 80°C/km, the minimum depth of the reservoir is estimated to be around 3 km.
