介绍了伸展体制下的拆离滑脱构造概念及大陆伸展模式。以渤海湾第三纪断陷盆地、焉者中生代盆地为例，探讨了大陆伸展过程中，拆离滑脱构造对盆地形成、沉积建造、油气成藏的控制作用。最后指出国际地学界有关盆地研究动向，已由传统的构造、沉积分析，逐步转向地球动力学、热力学分析．
The concept of detachment and slippage structure under extension system and the extension mode of the mainland are introduced. Taking the Mesozoic and Cenozoic basins of the Tertiary in the Bohai Bay as an example, the disintegration and detachment structures during the extension of the continent were discussed to control the basin formation, sedimentation and hydrocarbon accumulation. Finally, it is pointed out that the trend of basin research in international geosciences has shifted from the traditional tectonic and sedimentary analysis to the geodynamics and thermodynamics analysis.
