摘　　要：位于渤海湾盆地黄骅坳陷北部的白东构造带,受新构造运动影响形成了整体东西向"S"型展布,堑心组合内断层成弧形交错、南北对掉的"包心菜"状构造。笔者以局部构造变形特征分析为手段,从各层位上堑心构造组合的特殊现象分析出发,认为本区自第三纪以来是在右旋走滑拉分背景下伸展走滑作用的结果。The Baidong structural belt is located in the northern Huanghua depression of the Bohai Bay basin. It is a nearly E-W-directional S-type belt, exhibiting a cabbage-like structure. In the center of the graben, the structural styles comprise mainly N-S-trending distorted normal faults, which are intersected one by one to form a Y-shape ar- chitecture. Based on structural stress analysis and graben structural assemblage, we consider that the Baidong structural belt was formed in an extension-slipping setting related to the right-lateral strike-slip and pull-apart move- ment of the boundary faults since the Neogene.
