摘　　要：为了揭示黄骅拗陷新生代盆地原型、恢复盆地构造演化历史,运用油区构造解析理论,对黄骅拗陷新生代盆地构造样式及其演化进行综合分析,认为盆区存在伸展式和走滑式两种基本构造样式。在盆地尺度内,按断层几何学和运动学特点,伸展构造样式可进一步分为伸展拗陷、伸展拗断、地堑断陷、多米诺半地堑断陷、滚动半地堑断陷、复式半地堑断陷、跷跷板断陷、伸展断拗8种次级构造样式,并基本遵循伸展拗陷—伸展拗断—伸展断陷—伸展断拗演化序列,这种演化序列与岩石圈的流变学特征和递进伸展变形过程有关。走滑构造样式受深断裂走滑作用控制,可分为雁列式走滑构造和帚状断层组。In order to reveal Cenozoic basin prototype of Huanghua Depression and recover its structural evolutionary history,using the theory of structural analysis,this paper makes comprehensive analysis on Cenozoic structural style and its evolution in Huanghua Depression,and two basic styles are proposed in the paper,including extensional-type,strike-slip-type.In basin scale,according to the characteristic of geometry and dynamics,extensional structure type can be divided into eight secondary styles,including extensional depression,extensional downwarp-fault depression,graben fault depression,domino half graben fault depression,roll half graben fault depression,duplex half graben fault depression,seesaw fault depression and extensional fault-downwarp depression,and follows the evolutionary sequence of extensional depression-extensional downwarp-fault depression- extensional fault depression and extensional fault-downwarp depression.This evolutionary sequence is related to rheology feature and extension and deform of lithosphere;strike-slip-type is controlled by deep fault,and can be subdivided into en echelon strike-slip structure and fastigiated fault group.
