摘要：

Understanding the lithospheric thermal structure is an important basis for understanding the continental dynamics (i.e., tectonic deformation and evolution) of the continental lithosphere. It is also the core of studies on the thermal source mechanisms of geothermal fields. Most importantly, it can provide scientific guidance for the exploration and development of deep geothermal resources. The Cangxian uplift enjoys rich geothermal resources and favorable geothermal geological conditions. However, its lithospheric thermal structure is still unclear, which restricts the exploration and development of regional geothermal resources. Focusing on the Xianxian geothermal field in the middle part of the Cangxian uplift through the temperature measurement of a 4 000 m deep well and fine tests of geotechnical thermophysical properties, this study has ascertained the characteristics of the terrestrial heat flow and lithospheric thermal structure in the study area, thus filling the gap in terrestrial heat flow measurement. Moreover, this study has established a conceptual model of the lithospheric thermal structure of the study area and estimated the deep temperature and lithospheric thickness in the study area. The results show that the Xianxian geothermal field has a heat flow of 70.58 mW/m2, a burial depth of the Curie surface of about 24 km, a Moho temperature of about 749 ℃, and a lithospheric thickness of about 85-96 km. © 2023 China University of Geosciences.
