The study of geothermal genesis mechanism is the basis for the evaluation and effective development of geothermal field resources. On the basis of previous research results, the formation mechanism of geothermal field in Qikexing Township was analysed and the geothermal resources were evaluated by identifying geothermal anomalies in the area. In this paper, two geothermal anomalies were identified based on remote sensing inversion, soil chemical exploration, shallow temperature measurement and the main heat-control fractures, and the distribution characteristics and causes of hot springs were comprehensively studied by means of hydrogeochemistry and isotope analysis. The results show that the sources of geothermal water recharge are atmospheric precipitation and ice melt water in the vicinity. The cations of the geothermal water are mainly Na⁺, with an anionic ratio of 68.75%, followed by Ca²⁺ and K⁺; the anions are mainly SO⁴_2-, with an anionic ratio of 47.25%, followed by Cl^- and HCO₃^-; and the geothermal water is of the Cl·SO₄-Na(Ca) type. The geothermal wells are mainly distributed along the active fracture spreading direction in the form of beads, and the maximum depth of thermal storage cycle is 2393 m. The temperature of thermal storage ranges from 49.4 to 93.7 ℃, and the heat source mainly comes from the heat transfer of mantle channel flow, the heat generated by the decay of radioactive elements, the heat generated by magmatic activities and so on. The results of the evaluation of geothermal resources in the study area show that the total geothermal resources are 1.38 × 10¹⁹ J/a, equivalent to 4.71 × 10⁸ t/a of standard coal. This study mainly focuses on the distribution law of hydrothermal geothermal resources in Yanqi Qikexing town and the geothermal genesis, which can provide a reference basis for the development and utilisation of geo The study of geothermal genesis mechanism is the basis for the evaluation and effective development of geothermal field resources.

Evaluation of geothermal resources is the basis for sustainable development and utilisation of geothermal, and with the increase of global demand for clean energy, the research on geothermal resources evaluation has made remarkable progress at home and abroad. Qiao et al. 14 calculated the temperature and its distribution in different strata using geothermal methods based on the heat flow, geothermal gradient, and thermophysical properties to determine the geothermal resources potential of the Dongpu Depression; Simeneh Wassihun et al. 15 deeply analysed the distribution of geothermal resources and their relationship with subsurface geological structures in the Kobeti geothermal prospect in the Main Rift Valley, Ethiopia, through the linkage of surface and subsurface anomalies; Sun et al. 16 assessed the geothermal resources in the sedimentary basins of the Sichuan Basin by adopting a rapid computational method that fuses geological, geophysical, and geochemical data; Pei et al. 17 , He et al. 18 ., Chen et al. 19 and Li et al. Geothermal geological background of the study area Natural geographical conditions The research area was located southwest of the Yanqi Basin in Xinjiang. Its main landforms were the Zhongshan area, eroded In the process of migration, groundwater receives magmatic body activity, mantle heat and crustal radiothermal heating to form 49.4 ~ 93.7 ℃ hot water, and the circulation depth is between 1050 ~ 2393 m. Under the action of topographic height difference or corresponding water head difference, upwelling along deep faults and structural cracks in the form of thermal convection, and mixing underground cold water in the upwelling process, thus forming geothermal anomalies in appropriate parts or gush out of the surface to form hot springs (geothermal Wells). Surface heat flow method The surface heat flow method, which is based on the heat emitted from a geothermal field to the outside, including heat emitted to the air by rock conduction and heat emitted through hot springs, hot springs, vents, etc., usually gives only a minimum development potential for a small area, where heat emitted to the air by rock conduction can be estimated based on the measurement of the geothermal heat flow value.
