| 英文摘要 | The Sichuan basin, located in the western margin of the Yangtze block, is one of the most important oil-gas-bearing basins in China. The Late Himalayan period since 25Ma was an important period of tectono-thermal evolution in this basin, during which the basin was in a compressed and uplifted tectonic dynamical environment. In this study, we simulated the tectono-thermal evolution of the Sichuan basin during the Late Himalayan period based on 8 profiles crossing the whole basin. And meanwhile, the simulation results were effectively constrained by the present-day terrestrial heat flow. We used a 2D finite element method to resolve the 2D transient heat conduction equation (including an advection term), and introduced a modified model of the Airy equilibrium theory. The modeling results regionally reveal that the surface heat flow values of the Central Sichuan basin at 25Ma are relatively high, between 60 mW/m(2) and 64 mW/m(2); the values of the southwestern Sichuan are relatively low, between 60 mW/m(2) and 62 mW/m(2); and those of the northeastern Sichuan are the lowest, between 50 mW/m(2) and 54 mW/m(2). The spatial variations of the basal heat flow in this period are similar to the surface heat flow. The spatial distribution of heat flow is associated with deep dynamic processes beneath this region. The modeling results indicate that the uplift during the Late Himalayan period reduced the surface heat flow and basal heat flow of the Sichuan basin, and the reduction was influenced by the denudation rate, i.e. the bigger the denudation rate, the lower the heat flow is. |
