Research on Tectono-Thermal Evolution Modeling Method for Superimposed Basin with the Jianghan Basin as an Example

Tectono‐thermal evolution modeling based on geodynamic methods is an important method for studying sedimentary basin's thermal history. We restored superimposed basin's complex and long‐time evolution by using balanced cross‐section method, and inverted for its paleo‐heatflow by using multiple‐stage finite extensional and compressional strain rate method, with Yisui profile in the Jianghan Basin as an example. Finally, we calculated the paleo‐temperature of superimposed basin. Thus, we established a workflow of multiple‐stage extensional and compressional modeling, in which tectonic restoration, paleo‐heatflow inversion, lithosphere temperature reconstruction, and sedimentary basin temperature inversion are combined, and sedimentary basin's thermal evolution is coupled with that of the lithosphere.
