摘要
通过对松辽盆地构造反转的分析，把该盆地构造反转划分为３种类型；平面上分为４个反转构造带．结合中国东部含油气盆地构造样式和演化机制，认为松辽盆地的构造反转不是局部现象，它代表了中国东部裂谷盆地演化的普遍模式，并与构造圈闭、油气藏的形成密切相关．中国东部盆地重要的构造反转有４期；盆地内众多构造圈闭类型是多种地质应力联合作用和多期构造作用叠加的结果，而后期的挤压反转起到了加剧和定型作用．中国东部燕山—喜山期几次挤压反转与板块运动方向的改变及区域左行。
Three patterns of structural inversions in Songliao Basin have been recognized. The inversion structures are distributed in four inversion belts, and each of the belts is characterized by distinct inversion deformation. The structural inversions in Songliao Basin might represent a common model, rather than a local feature, of structural evolution of the rift basins in eastern China according to the discussions on the inversions in Songliao Basin and the structural styles and evolution mechanisms of other basins in eastern China. The structural traps and hydrocarbon accumulations in these basins are colsely related to the inversions. The basins in eastern China are supposed to have undergone four main periods of inversion, superimpositions of multiple geological strains and structural activities in different periods resulted in the various kinds of structural traps in eastern China, which were intensified and finally developed by late compressive inversions. It is also suggested that the several compressive inversions in eastern China, during the Yanshanian and Himalayan epoches, had relationship to the mutual transitions between clockwise and counterclockwise wrench strain fields due to the changable plate tectonic movements.
