| 摘 要： | 郯庐断裂带是亚洲东部著名的走滑断裂活动带，经过多年研究，取得了一系列重要成果。以其中的渤海海域辽东带中南部为研究对象，从沉积体系、沉积中心和层序构型三方面分析沉积对断裂走滑活动的响应。郯庐断裂走滑活动对沉积体系和沉积中心的展布特征与迁移规律具有控制作用。具体表现为：走滑活动错开先期形成的沉积体系和沉积中心；使同期形成的沉积体系和沉积中心随时间发生横向迁移；使沉积区发育的三角洲扇体进积特征不明显。断裂走滑活动通过改变可容空间大小，制约层序构型和沉积相分布模式。

| Abstract: | Tan-lu fault is a famous strike-slip fault in East Asian and many significant achievements have been made after years of study. This article discusses the response of the fault activity based on study of the influence to the sedimentary system，deposition center and sequence stratigraphic in central and south part of the east Liao-dong Bay area，Bohai Sea. It is revealed that the Tan-lu fault activity has controlled and modified the distribution and migration of the sedimentary system and deposition center:(1)the strike-slip movement faulted the previously formed sedimentary system and depositional center;(2)the fault activity leads to the horizontal migration of sedimentary system and depositional center formed in the same period;(3)the fault activity makes the progradation characteristic of the delta unobvious. Fault activity has influenced the sequence configuration and internal composition of the sedimentary facies distribution model by changing the accommodation space. |
