| 摘 要： | 渤海湾盆地地区中生代构造演化与样式始终不明朗,特别是对燕山期变形始终存在争议,故选择黄骅坳陷中区中生界作为重点剖析对象,通过大量地震剖面的解释和平衡剖面技术复原古构造演化的研究,并结合前人研究成果和区域构造背景,提出黄骅坳陷中区中生代演化过程可大致分为4个阶段:印支晚期东西向宽缓褶皱及后期逆冲构造变形期、燕山早期挤压走滑构造变形期、燕山中期继承性挤压与右旋张扭构造变形期、燕山晚期—喜山期区域性伸展构造变形期。

| Abstract: | The Mesozoic structural pattern and evolution of the Bohai Bay basin is debated until now.Espe- cially the Yanshanian deformation pattern is a key problem.We try to select the middle range of the Huan- ghua Depression of the Bohai Bay basin to study structures of this area,using a large number of seismic profiles.The Mesozoic evolution in the middle range of the depression can be mainly divided into four peri- ods by using the balanced cross-section technique to reconstruct palaeo-structure in conjunction with tec- tonic setting.The first-generation structures are gentle east-west-plunging folds and the following east- west-striking thrust formed in the late Indosinian.The second-generation strustures are NNE-plunging folds and the following strike-slip faults formed in the early Yanshanian.In the middle Yanshanian,a se- ries of structures were under the ongoing compression,subsequently the dextral normal-slip faults formed under the extension.At last,some normal faults in this area were under regional intensive extension from the late Yanshanian to the early Himalayan. |
