Geochemical nature of the geothermal water from Lanzhou Basin: Implications for the genesis of shallow helium-bearing fluids
Published 2025-06-01“…Compositions of the dissolved gas and the geochemical nature of the groundwater jointly suggest that the associated helium in the geothermal water from this well is a product of the radioactive decay of Th-U elements in the basement rocks of the basin. Comprehensive analysis indicates that the upward migration and accumulation of ancient helium-bearing water from the basement into shallow geothermal reservoirs along fault zones under the background of tectonic uplift is the key process for the enrichment of associated helium in geothermal water in the Lanzhou Basin.…”
