摘　　要：论文对吉林东部中新生代盆地群的地层分布特征、岩石圈断裂带的形成和后期活动特征、中新生代盆地群的形成和演化过程进行了研究,结果表明,鸭绿江断裂带、佳—伊断裂带与敦—密断裂带控制着断裂带内及两侧的中生代沉积建造与岩浆岩分布,并对区内中新生代盆地群的形成和演化具有明显的控制作用,并根据区域构造演化过程和断裂带的活动特征对盆地群的成盆与构造演化阶段进行了划分,具体包括盆地基底改造阶段(T—J21)、佳伊和敦密控盆断裂形成阶段(J22—J3)、白垩系断陷盆地形成阶段(J3末—K1)、抬升剥蚀阶段(K2)、走滑裂陷及新生代盆地形成阶段(E)和玄武岩喷发及抬升剥蚀阶段(N—Q)6个演化阶段。Based on the study of the Stratigraphic distribution,formation and late-stage activity of lithospheric fault zones,formation and evolution of Mesozoic and Cenozoic basin groups in eastern Jilin Province.The results show that the Yalujiang fault zone,Jia-yi fault zone and Dun—Mi fault zone control the Mesozoic sedimentary formation and magmatic rock distribution in and on both sides of the fault zone.Faults play an important role in controlling the formation and evolution of Mesozoic and Cenozoic basins.The basin formation and tectonic evolution stages of basin groups are divided according to the regional tectonic evolution process and the active characteristics of fault zones,including the basin basement transformation stage(T-J21),The formation stage of Jiayi and Dunmi basin-controlled faults(J22-J3),Formation stage of Cretaceous fault basin(J3-K1),Uplift denudation stage(K2),Evolution models of strike-slip rift and Cenozoic basin formation stage(E)and basalt eruption and uplift-denudation stage(N-Q).This study not only explores the basin formation and tectonic evolution of the eastern Jilin basin group,but also provides a scientific basis for the exploration of oil and gas resources in the Mesozoic and Cenozoic basins in this area.
