| Abstract | Tapoban is one of the 112 hot spring localities of Northwest Himalaya, known for its copious borehole discharges. Thermal waters, though having temperatures of 80" to 90?C, have characteristically very low TDS content of < 500 mg kg-'. This is because fluids have mainly interacted with quartzite. Stable isotope data provide unequivocal evidence that recharge zones of thermal discharges are located at altitudes of > 3000 m. A simple model of normal gradient heating offers the most plausible explanation for the thermal anomaly of the area. |
