Lithospheric Thermal Structure in Jinggangshan City: Implications for High Geothermal Background

Jinggangshan City, which is located in the southwestern part of Jiangxi Province, rich hot springs. However, lack geothermal studies has limited exploration and utilization resources this city. This study estimated terrestrial heat flow City through well logging analyses rock thermal conductivity production. Based on surrounding geoscience transect Crust 1.0 model, constructed a one-dimensional lithospheric structure by solving steady-state conduction equation. Furthermore, deep temperature distribution was obtained to better understand geodynamic condition The results show that city around 83.52 mW/m 2 , indicating high background for formation resources. According mantle contributes more ( q m /q c > 1) than crust. Mohorovicic discontinuity (the Moho) 671.7°C, consistent with below Tanlu fault (620–690°C). Moreover, calculated depth Curie surface (585°C) 27 km, isotherm from aeromagnetic data. consistency verifies validity study. In summary, plays an important role City.
