Hydrogeochemical and isotopic analysis for interpreting the formation of the complex geothermal system in the Guide Basin, Northeastern Tibetan Plateau.

ABSTRACT: The Guide Basin, located in the northeastern Tibetan Plateau, is rich in geothermal resources. However, whether the genesis of all geothermal waters in the basin is consistent remains an unresolved question. To clarify the geothermal system in this area, this study investigated the hydrogeochemical and isotopic characteristics of geothermal waters, combined with an analysis of the distribution and properties of regional faults. The study analyzed the processes controlling the chemical composition of thermal waters and the reservoir temperatures, ultimately creating a conceptual model of geothermal fluids. The results indicate that the geothermal waters in the Luohantang and Zhacanggou areas are classified as Na-SO4·Cl type, while those in the Xinjie area are classified as Na-HCO3 and Na-HC
