Geochemistry of the thermal waters of Salbardi and Tatapani, India

Geochemical studies have been carried out on water samples collected from Tatapani and Salbardi hot springs. The waters of these hot springs are classified as NaHCO₃ type. Waters in deep aquifers are associated with quartz, shale and clay terrains. Activity studies of the minerals and the waters present in the aquifers suggest that the thermal waters are within equilibrium with montmorillonite, kaolinite and quartz at about 150°C. The geochemical thermometers also estimate 150 ± 10°C as aquifer temperatures for Tatapani and Salbardi.
