| 摘 要： | 渤海湾盆地临清坳陷东部自中生代以来经历了多次构造运动，不同构造时期盆地性质也不相同。本次研究对临清坳陷东部自晚侏罗世以来的构造演化历史进行了分析，恢复了上侏罗统—下白垩统的地层剥蚀量和原始地层厚度，在此基础上结合同一时期的断裂系统图，对盆地发育特征进行了初步研究。结果表明：临清坳陷东部晚侏罗世—早白垩世处于断陷盆地发育阶段；地层剥蚀程度的强弱主要受燕山晚期运动所形成的各种构造的控制，剥蚀厚度呈NE向大小相间分布；晚侏罗世—早白垩世盆地展布方向为NNE向，地层展布主要受断层控制，厚度中心均位于断层上盘。

| Abstract: | Eastern Linqing Depression of the Bohai Bay Basin has experienced a number of tectonic movements since the Mesozoic and the basin nature is different from each other in different tectonic stage.This article analyzed the tectonic evolution history since the Late Jurassic and restored the denuded thickness and the original thickness of the Upper Jurassic-Lower Cretaceous in eastern Linqing Depression. Based on the above results，this article studied the development characteristics of the Late Jurassic-Early Cretaceous basin combined with the fault system diagram of the same period.Eastern Linqing Depression is a rift basin in the Late Jurassic-Early Cretaceous stage.The denuded thickness is mainly controlled by the structures formed by Yanshan tectonic movement and characterized by phase distribution in NE direction.The Late Jurassic-Early Cretaceous basin distributed in the NNE direction and strata distribution is mainly controlled by faults.The thickness centers are located in the hanging wall. |
