Geochemical investigations on thermal and cold springs at Dumka District, Jharkhand, India

Singh, Hemant K. and Chandrasekharam, D. and Gurav, Trupti and Singh, B. (2014) Geochemical investigations on thermal and cold springs at Dumka District, Jharkhand, India. International Journal of Earth Sciences and Engineering, 7 (1). pp. 190-194. ISSN 0974-5904


Abstract

There are various thermal and cold springs located in Dumka district of Jharkhand, India. These springs are issuing through the Chotanagpur Gneissic Complex (CGC) and Rajmahal trap. Surface temperatures of the thermal springs range between 42° to 70°C and are near neutral to moderately alkaline(pH = 6.9 - 9.5) in nature. Position of thermal water in Piper diagram suggests that the thermal springs are Na-Cl type and the chemistry of thermal springs is compatible with the host rock of the area. Cold springs of the area are near neutral (pH = 7.4-7.5) in nature and fall in Ca-HCO3 field in Piper diagram, indicating that the circulation of the cold springs is through sedimentary formation. Estimated reservoir temperature based on chemical geothermometers ranges between 92° to 138°C; indicating that these thermal springs are suited for low enthalpy geothermal system.
