| 英文摘要 | The Tan-Lu fault zone is one of the most important faults in East Asia. It has received extensive attention of many fields such as structural geology, mineralogy, and seismology. However, few geothermal studies on this structure have been made so far. This work conducted temperature measurement on 7 wells systematically in the southern Tan-Lu fault zone. Thermal conductivity of 142 cores and 13 outcrop samples for these wells were tested by the optical scanning method and 6 high-quality heat flow data were obtained. Combined with the published heat flow and seismic profiles, we obtained the lithospheric structure of the southern Tan-Lu fault zone. The study shows that the current temperature gradient in the study area increases from south to north, ranging from 21. 8 to 30. 3 degrees C . km(-1). The heat flow value is between 44. 0 similar to 81. 7 mW . m(2), with an average of 61. 4 +/- 10. 8 mW . m(2), represnting a normal geothermal heat flow rather than a thermal anomaly belt. The maximum heat flow value appears in the Continental Scientific Drilling Well ZKO3 in the Luzong Basin and the extremely high heat production of rocks in the shallow upper crust is probably the main factor for such a high heat flow. The bottom boundary of the shallow earthquake seismic zone in the southern Tan-Lu fault zone is well coupled with the 350 degrees C isothermal surface, indicating the difference in deep structure. |
