通过不整合、地层缺失、岩浆活动、断裂活动等分析，以及与邻区构造事件进行对比，认为台西盆地新生代构造事件主要有晚白垩世晚期—古新世早期（距今约70M～60Ma）、古新世末—始新世初（距今约54M～51Ma）、始新世晚期—渐新世早期（距今约42M～32Ma）、晚中新世—上新世初（距今约10M～5Ma）和上新世末—中更新世（距今约2．5M～1Ma）。它们在区内表现明显，依次反映了台西盆地从裂谷出现（晚白垩世晚期—始新世中期）到成熟（始新世晚期—中中新世）、最后衰亡（晚中新世—第四纪）的演化过程。
Through the analysis of unconformity, stratigraphic loss, magmatism and fault activity, and the comparison with the tectonic events of the adjacent areas, it is concluded that the Cenozoic tectonic events in the western Taixi Basin mainly occurred in the late Late Cretaceous-Early Paleocene (about 70-60 Ma ), The late Paleocene-Early Eocene (about 54M ~ 51Ma ago), the late Eocene-Early Oligocene (about 42M ~ 32Ma ago), the late Miocene-Early Pliocene About 10M ~ 5Ma) and the end of the Pliocene - Middle Pleistocene (about 2.5M ~ 1Ma ago). They are evident in the region, which in turn reflects the evolution of the Taixi Basin from rifting to late maturity (Late Eocene to Middle Miocene), from Late Cretaceous to mid-Eocene (late Late Miocene- Quaternary) evolution.
