摘要
渤海湾新生代盆地经历了早第三纪裂陷沉降和晚期第三纪-第四纪后裂陷热沉降两个阶段。基本完成了一个完整的裂陷作用旋回。早第三纪裂陷作用包括三个裂陷伸展期,它们分别相当于孔店级-沙四段、沙三段、沙二段-沙一段-东营组等三套地层的发育时期,各裂陷伸展期的构造运动学特征有一定的差异,反映在伸展构造样式的变化上,大致可归纳为由多米诺式正断层系统向铲式正断层系统、坡坪式正断层系统的演化序列及由非旋转平面式正断层系统向铲式正断层系统、坡坪式正断层系统的演化序列两个演化模式。
The tectonic evolution of Bohai Bay basin province can be divided into two stages of rifting and post-rifting. and basically completed a cycle of taphrogenesis.The riftingstange during Paleogene is composed of three extensional periods which correspond theformations of Kongdian and 4th number of Shahejie,3rd number of Shahejie,and 2nd-1stnumbers of Shahejie and Dongying. There are obvious disparity in tectonic styles andkenematics between the three extensional periods.The evolution of extensional tectonics caninclude 2 paths:(1) from domino systems to listric systems and ramp-flat normal faultsystems:(2)from non-rotation normal fault systems to listric systems and ramp-flat normalfault systems.
