摘　　要：沉积盆地构造热事件的研究是盆地热演化史研究的热点及前缘领域。介绍了低温热年代学方法、古温标法及地球动力学模型方法研究中的新进展。叠合盆地构造-热演化史恢复是热演化史研究的前缘领域及难点,低温热年代学测年技术已成为叠合盆地构造-热演化史恢复的重要方法。中国普遍发育叠合盆地,叠合盆地古地温场经历的后期叠加改造普遍存在,叠合盆地的后期盆地对前期盆地的古地温场信息有抹去或掩盖作用。从叠合盆地叠加与改造对古地温场产生影响的角度出发,根据叠合盆地不同演化阶段地温场信息记录、保持及后期叠加改造情况的不同,结合多种古地温研究方法,以正确的地质模型及大量的实际地质资料为约束,提出分演化阶段真实恢复叠合盆地热演化史的新思路及方法。Tectonic-thermal event in sedimentary basin is a research hotspot and leading edge of basin thermal evolution history.The new developments of low temperature thermochronology,geothermometer and geodynamics model methods on the thermal evolution history in sedimentary basins were introduced.Reconstruction of tectonic-thermal evolution history of superimposed basins is one of the frontiers and difficulties in the research of thermal evolution history,and the dating technology of low temperature thermochronology is an important method for the reconstruction of tectonic-thermal evolution history of superimposed basins.A lot of superimposed basins are located in China,and the paleogeothermal fields of superimposed basins are generally superimposed and transformed in late stage,the paleogeothermal field information ofsuperimposed basins in early stage is erased or covered by the basins in late stage.From the perspective of the effect of superimposition and transformation of superimposed basins on the paleogeothermal field,according to the differences of geothermal field information record,maintenance and late superposition and transformation of superimposed basins in different evolution stages,combined with various geothermal methods,taking the correct geological model and a large number of actual geological data as constraint,the new thought and method for the real reconstruction of thermal evolution history of superimposed basins were purposed in different evolution stages.
