【摘要】 在对东北地区佳木斯隆起与周缘中新生代盆地群的野外地质调查和地震剖面综合解释的基础上,结合近年来的研究成果,确定了研究区的盆山耦合关系:在早白垩世发生NW—SE向伸展作用,形成广泛发育呈NE向展布的伸展盆山耦合系统;在晚白垩世受到NWW—SEE向挤压作用,形成NE—NNE向的逆冲推覆构造与挤压坳陷型盆地并存的盆山耦合系统;在渐新世—中新世受到近NS向挤压作用,不仅使白垩纪形成的NE—NNE向构造和盆地受到叠加改造,而且形成了与NS向挤压作用相伴产生的挤压坳陷型盆地,构成了广泛发育的近EW向展布的隆起和挤压坳陷盆地并存的盆山耦合系统。佳木斯隆起在中新生代的隆起作用主要是晚白垩世、渐新世—中新世2次逆冲作用叠加的结果。研究区自白垩纪以来始终处于活动大陆边缘的大地构造背景。上述3个阶段的盆山耦合机制与太平洋板块向欧亚板块的俯冲作用有关。

【Abstract】 On the basis of the field investigation and geological interpretation of seismic profiles of Jiamusi uplift and surrounding Mesozoic-Cenozoic basins in Northeast China,combined with recent research results,the basin-mountain coupling are determined: the study area occurred NW-SE extension,formed NE trending extensional basin-mountain coupling system in the Early Cretaceous;suffered NWW-SEE compression,formed the NE-NNE trending compressive basin-mountain coupling system which consists of thrust and compressive basin in the Late Cretaceous;experienced nearly NS trending compression,not only the Cretaceous formation of NE-NNE trending structures and basins were superimposed,but also formed the nearly EW trending compressive basin-mountain coupling system which consists of uplifts and compressive depression basins in Oligocene-Miocene.The uplifting of Jiamusi uplift in Mesozoic-Cenozoic is mainly the results of twice thrusting superposition in Late Cretaceous and Oligocene-Miocene.The study area has always been active continental margin tectonic setting since the Cretaceous,the above three stages of basin-mountain coupling are related with the subduction of the Pacific plate to the Eurasian plate.
