Hydrogeochemical characteristics and genetic analysis of hot springs in Luxi basin, western Yunnan Province

More Information
  • There are complex structures of aquifer and numerous hot springs in Luxi basin. The authors carried out geological, hydrogeological and hydrogeochemical survey of two typical hot springs(the Fapa hot spring and Mangliu hot spring) to probe into the doubtful points in the analysis of the hot springs, and made a comparison with hot springs formed under different conditions. On such a basis, the genesis of the hot springs was further analyzed. The results show that the Fapa hot spring and Mangliu hot spring are typical fault hot springs, their sources should be precipitation and endogenous high-temperature fluids, and the heat-storing layer is composed of dolomite and dolomitic limestone of the Permian Shazipo Formation Jurassic and Mengga Formation. It is estimated that the thermal energy storage temperature could reach 160℃ at the depth of 2000m.
