Geochemistry of Thermal Springs from Bhutan Himalaya

Geothermal gases, water and local meteoric water samples from six prominent geothermal areas of Bhutan. Himalayas were collected and analysed for H₂, He, O₂, N₂, CH₁, CO, NH₃ , CO₂ and H₂S gases, major and minor anions and cations along with pH, Specific Conductance, TDS and total hardness of water respectively. Reservoir temperatures calculated by geothermometry puts these hot springs under intermediate enthalpy resources of geothermal system. The geochemistry of thermal waters divides the hot springs of Bhutan into two categories belonging to Lodiai and Gasa type hot springs.
