| 摘 要： | 通过对燕山东段～下辽河盆地中新生代断裂演化分析，认为中新生代该区共经历了中三叠世末，早侏罗世末，晚侏罗世末，白垩纪末和老第三纪末５期挤压作用。每期挤压作用都形成相应的挤压构造形迹，使得早期盆地萎缩或消亡，或对早期盆地进行改造使其反转。此外，该区还曾经历了中晚侏罗世，白垩纪和新生代３个明显的伸展作用阶段，形成中晚侏罗世断裂盆地，白垩纪断陷盆地和新生代裂谷盆地，构造演化过程中挤压作用和伸展作用交替出现

| Abstract: | The analysis of structural evolution in the East Yanshan Area and Xialiaohe Basin since Meso-Cenozoic shows that this area has experienced five times of compression deformation (the end of Middle Triassic, Early Jurassic, Late Jurassic, Cretaceous and Paleogene) which resulted in withering or disappearing of the early basins and basin reversion and form ed compression structures, and three extensional periods in which Middle and Late Jurassic fault basin, Cretaceous fault basin, and Cenozoic rift basin were formed respectively. The compression and extension occurred alternatively, compression structure and extensional structures developed alternatively in the structural evolution. |
