Physicochemical evolution of the thermal springs over the Siwana Ring Complex, western Rajasthan

Singh, Hemant K. and Garg, G. C. and Chandrasekharam, D. and Gurav, Trupti and Singh, B. (2014) Physicochemical evolution of the thermal springs over the Siwana Ring Complex, western Rajasthan. Journal of the Geological Society of India, 84 (6). pp. 668-674. ISSN 0016-7622


Abstract

The chemical composition of thermal springs from Siwana Ring Complex (SRC) of Barmer district, Rajasthan, India has been investigated for the first time. These springs are near neutral to mildly alkaline (pH = 6.8 to 7.8) in nature with surface temperatures varying between 31 to 39 °C. Piper diagram suggests that these thermal springs are dominated by Ca-HCO 3 type. Experimental results of water-rock interaction at 100 °C indicate that the thermal springs are circulating through tuff and a sedimentary formation extensively controlled by ring dykes of granites, felsic volcanics and mafic dyke and the fault systems associated with the host rock. Groundwater and thermal springs show similar characteristics. Estimated reservoir temperature suggests that Siwana area geothermal system is a low enthalpy system. Heat flow values of the area range from 83 to 205 mWm −2 , promise a viable potential for Enhanced Geothermal System (EGS).
