| 英文摘要 | Geologically the Xiongan New Area is within the Jizhong Depression of Bohai Bay Basin. The study area consists of 3 lower-order structural units : the Rongcheng Uplift, the Niutuozhen Uplift and the Gaoyang Uplift. Temperature logs from 8 boreholes and thermal conductivity measurements of 108 rock samples are newly acquired. Integrated with previous research, the present geothermal gradients and heat flow distribution within the Xiongan New Area are analyzed. Results shows that in vertical direction the geothermal system can be divided into two parts : the upper sedimentary layer with the geothermal gradients ranging from 25. 2 similar to 58. 9 degrees C . km(-1), and the bedrock layer with geothermal gradients around 5 degrees C . km(-1). In addition, the temperature gradient distribution is associate with the structural units, the Niutuozhen Uplift has the highest geothermal gradient which ranges from 46. 5 degrees C . km(-1) to 58.9 degrees C . km(-1); the geothermal gradient is slightly lower in the Rongcheng Uplift with the values vary from 32. 0 degrees C. km(-1) to 40. 9 degrees C . km(-1), the depression and low uplift Area has the lowest geothermal gradient in which the only one borehole shows the average geothermal gradient of 25. 2 degrees C . km(-1). The heat flow map which is conducted through collecting published data shows the similar tendency, the uplift area has the higher heat flow value than the depression. The high present temperature field of Xiongan New Area has great associated with the back-arc tectonic background. The convection of the groundwater, the combination of the stratum and the well-developed faults that all contribute the high present temperature field of this area. |
