摘要：As a key scientific issue for geological research, the reconstruction of tectonic uplift process is of great significance to the exploration and evaluation of mineral resources. The existing research methods have some applicability and limitations, and it is difficult to establish quantitative relationship between forward and inversion results. In this paper, we applied the thermal-kinematic method, which uses discrete element numerical simulation to record the motion paths of discrete elements during deformation and provides geological constraints for the thermal history reconstruction of thermochronological samples. This method achieved the quantitative coupling between tectonic deformation simulation and thermochronological analysis, and showed great potential in the research of tectonic uplift process. We focused on the multilayer detachment folding in the eastern Sichuan basin and reconstructed the uplift and deformation process of the Fangdoushan-Qiyueshan anticline within 170~70 Ma. The thermal-kinematic analysis showed that the pre-existing Qiyueshan fault connects the deep detachment surface and the shallow detachment layer. The western Hunan-Hubei fold belt germinated at 170~110 Ma. During 140~110 Ma, the fault-propagation folding gradually transformed into fault-bend folding. The Qiyueshan anticline began to develop, slightly earlier than the Lichuan synclinorium. From 110 Ma to 90 Ma, the Fangdoushan anticline developed and the ejective fold belt appeared. During 90~70 Ma, the scale of ejective folds gradually increased and the Lichuan synclinorium became tighter. The forward modeling establishment, geothermal gradient calculation, 3D modeling technology and stress evolution analysis are the key factors that restrict the development and improvement of the thermal-kinematic method.
