Saxena V., D'Amore F. Aquifer chemistry of the Puga and Chumatang high temperature geothermal systems in India. In: Journal of Volcanology and Geothermal Research, vol. 21 (3-4) pp. 333 - 346. Elsevier, 1984.
Results of a chemical study of the fluids from drill holes and hot springs of Puga and Chumatang areas in the northwestern part of the Himalaya are presented and discussed in this paper. The thermal waters of Puga and Chumatang are of Na-HCO3-Cl and Na-HCO3 types, respectively. A comparison between these waters, their chemical classification and activity studies suggest a flow path within a quartzitic-schistose basement, containing quartz, K-feldspar and illite, and in clayey terrains containing montmorillonite and illite. The chemistry of thermal waters also indicate their association with magmatic activity. The chemical geothermometers indicate the possible existence of a geothermal reservoir at Puga with temperature ≈250C. The Chumatang area has a comparatively cooler reservoir with a temperature of 150180C.
