| Characteristics and Heat Source Mechanism of Geothermal Resources in Qianshan Area of Ji’an, Jiangxi Province |
| The Qianshan geothermal field, located in the southwest of Wugongshan in the north branch of Luoxiaoshan, is the key area to study the geothermal resources of Wugongshan. Based on the methods of regional geology, geological characteristics of the study area, thermal physical parameters, hydrochemical characteristics and zircon isotopes, this paper mainly analyzes the characteristics of the geothermal system in Qianshan area, and deeply studies the tectonic background and heat source mechanism of Qianshan geothermal. The results show that: (1) the Heping-Sanjiang fault in the NE-SW direction is an important thermal conduction and thermal control structure in Qianshan geothermal; (2) The characteristics of water chemistry and isotopes indicate that both geothermal water and cold water in Qianshan area are supplied by atmospheric precipitation. (3) The thermal conductivity characteristics of the Early Silurian biotite monzogranite show that the granite has good thermal conductivity and heat accumulation ability. (4) The radioactive heat generation rate of biotite monzogranite is low with long history, which indicates that the contribution of radioactive element heat generation and magmatic waste heat to heat source is very small, and the heat source of Qianshan geothermal is mainly from the depth of the crust. This study can provide important enlightenment for the genesis and rational development and utilization of geothermal resources in Wugongshan area. |
