| 英文摘要 | Based on temperature measurements in 10 boreholes and thermal conductivity determination of 61 rock samples, 10 heat flow values were obtained for the eastern subdepression of Laohe basin. The thermal history of eastern subdepression was reconstructed based on the vitrinite reflectance (Ro) data. The results show that the mean geothermal. gradient and thermal conductivity are about 36.5 degreesC/km and 1.667 W/ (m . K) respectively, and the corresponding heat flow ranges from 49.5 mW/m(2) to 70.0 mW/m(2), with a mean of 58.0 mW/m(2). The eastern subdepression experienced a much higher heat flow period from 43Ma to 25Ma. After reaching the maximum heat flow of similar to 82 mW/m(2) at 25Ma, the subdepression cooled down to the present-day heat flow of similar to 60 mW/m(2). Structural subsidence analysis shows that the subsidence of eastern subdepression is divided into two phases: earlier syn-rift phase (25 similar to 43Ma) and late thermal subsidence phase (since 25Ma). The lower present-day heat flow and the higher palaeo-heat flow corresponding to structual subsidence stages as well as the typical rift subsidence style provide some insight into the tectonothermal evolution of the basin. |
