  • Hot spring or a thermal spring is a spring with water at temperatures substantially higher than the air temperature of the surrounding region.
  • Most hot springs discharge groundwater that is heated by shallow intrusions of magma (molten rock) in volcanic areas.
  • Some thermal springs are not related to volcanic activity.
  • In such cases, the water is heated by convective circulation.
  • This means that the groundwater percolating downward reaches depths of a kilometre or more where the temperature of rocks is high because of the normal temperature gradient of the Earth’s crust—about 30 °C (54 °F) per kilometre in the first 10 km (6 miles).
  • Major hot springs in India:
    • Panamik in Nubra valley, Ladakh.
    • Kheer Ganga hot water spring, Himachal Pradesh
    • Gaurikund, Kedarnath, Uttarakhand.
  • The study suggested that CO2 in these thermal springs are sourced from metamorphic DE carbonation of carbonate rocks present deep in the Himalayan core.
