Abstract

To meet the increase in global energy consumption in an eco-friendly and sustainable manner more emphasis has been put on non-conventional energy resources, such as geothermal energy. India aims to significantly increase the contribution of geothermal energy to its energy mix. In order to do so, a thorough investigation into the geothermal resources of India is of utmost importance. Here we report the hydrochemistry and stable isotope systematics of thermal springs located in the state of Odisha, Eastern India, to evaluate the feasibility of harnessing the geothermal reservoirs. Water chemistry and stable isotope ratios of surface-, non-thermal and thermal water were studied to access the origin and chemical evolution of the thermal waters. The waters had a pH of 5.9 to 8.6 and a suggested meteoric origin based on their δ¹⁸O and δD ratios. Chemical geothermometers indicate reservoir temperatures in the range 96–128°C, caused by a high radiogenic heat production at depth coupled with the deep circulation of meteoric water through faults. Processes such as water-rock-interaction, mixing of thermal water with the shallow groundwater and mineral precipitation and dissolution were found to be responsible for the chemical evolution of the thermal waters.
