基于地球动力学的构造-热演化方法是沉积盆地热史研究的重要方法之一.本文以江汉盆地宜随大剖面为例,采用平衡剖面方法对叠合盆地复杂、漫长的演化历史进行构造恢复,采用多期有限拉张-挤压应变速率法进行古热流反演,最后得到盆地的古地温场.由此,建立了构造恢复-盆地基底热流反演-岩石圈尺度温度结构-沉积盆地尺度温度结构的多期伸展、挤压模型的热模拟方法流程,实现了岩石圈尺度的热模拟与盆地尺度的热模拟相结合.

Tectono-thermal evolution modeling based on geodynamics 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 its paleoheatflow 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 restruction, and sedimentary basin temperature inversion are combined, and sedimentary basin's thermal evolution are coupled with the lithosphere's one.
