摘要
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 Liaodong 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.
