| 摘 要： | 根据地层的抬升剥蚀(或沉降沉积)与古地温降低(或升高)之间的关系,通过磷灰石裂变径迹热史模拟的方法和其他地质资料,精确地确定了松辽盆地新生代的不整合和依安组、大安组、泰康组等地层沉积开始和结束的时间。松辽盆地新生代存在3次抬升和3次沉降:65.50~53.49 Ma盆地降温、抬升,产生依安组和白垩系地层之间的不整合面;53.49~40.31 Ma盆地升温、沉降,依安组沉积;40.31~36.18Ma盆地降温、抬升剥蚀,产生大安组和依安组之间的不整合面;36.18~5.83 Ma盆地升温、持续沉降,大安组沉积;5.83~1.79 Ma盆地降温、抬升剥蚀,产生泰康组与大安组之间的不整合面;1.79~?Ma盆地沉降,泰康组沉积。确定了依安组是始新统早、中期的地层,起止年龄为53.49~40.31 Ma;大安组是始新统末期—中新统的地层,起止年龄为36.18~5.83 Ma;泰康组是更新统的地层,开始年龄为1.79 Ma。 |

| Abstract: | Based on the relationship of stratum uplifting(or sedimentation) and rising(or falling) of paleotemperature,and the thermal history simulation of apatite fission track,beginning time of Cenozoic unconformity and sedimentation of Songliao Basin was confirmed here.Thermal history was also revealed accurately,that there are three episodes of alternative uplifting and subsidence: falling temperature with basin uplifting during 65.50-53.49 Ma,rising temperature with basin sedimentation during 53.49-40.31 Ma;second falling temperature with uplifting and denudation during 40.31-36.18 Ma,second rising temperature with successive sedimentation during 36.18-5.83 Ma;third falling temperature with uplifting and denudation during 5.83-1.79 Ma,and last sedimentation during 1.79-?Ma.Result shows that Yi'an Formation is the early-mid part of Eocene with the age of 53.49-40.31 Ma,Daan Formation belongs to the terminal of Eocene and Miocene from 36.18 Ma to 5.83 Ma,and Taikang Formation is a stratum of Pleistocene with the beginning age of 1.79 Ma. |
