摘要

摘要: 渤海宵盆地是一个新生代裂陷盆地.综合分析盆地区的岩石圈结构及盆地构造特征,大陆岩石圈的伸展变形机制可理解为上部以简单剪切伸展变形为主、下部以纯剪切伸展变形为主的“双层或多层分层伸展模式”.盆地区的构造演化过程中的“事件”序列表明,地幔热作用是控制盆地区裂陷伸展的动力学过程的主要因素,而板块边界作用力传递到盆地区的区域应用场则是深断裂发生走滑活动的动力源.

Abstract: The Bohai bay Basin is a Cenozoic rifting one.Based on a synthetic study of the litho-spheric structure and basinal tectonic characteristics of the basinal area,the extensional deformation of the continental lithosphere can be interpreted as a double or muliple layered extensional pattern, which is dominated by simple shear extensional deformation in the upper part and pure shear extensional deformation in the lower part. Thermal action withinthe mantle is a major factor which controls thc dynamic process of rifting extension in thebasinal area, as shown by the "event" sequences of the tectonic evolution proces,in thebasinal area. Nevertheless, the strike-slip of the deep fault is driven by regional stressfield formed by plate boundary effort transferring to the basinal area.
