中文摘要：

通过对区域地质、地层厚度、沉积特征以及断裂活动强度等资料进行分析，研究了济阳坳陷惠民凹陷不同时期的构造活动特征与沉积中心迁移规律，阐明了其动力学机制，并对沉积中心进行了重新厘定，提出了圈定沉积中心的具体方法。研究结果表明：惠民凹陷新生代存在东、西两个动态变化的沉降中心和沉积中心，除Es4期外沉积中心与沉降中心基本吻合，Es4期沉积中心已迁移到临邑西南，而沉降中心仍在滋镇西；Es4—Es3期是沉降中心迁移的重要转折期，主要发生南北向迁移，Ek—Es4和Es3—Ed时期以东西向迁移为主；西区沉积中心的迁移轨迹呈“S”形，东区为逆时针迁移。控凹断裂主要在Ek和Es4期活跃，Es3—Ed期则是控洼断层占据主导。无论是控凹断裂还是控洼断裂均受NNW向伸展构造以及兰聊、郯庐断裂右行走滑作用控制，这与太平洋板块向欧亚板块俯冲速度和角度变化引起的地幔对流及印度板块的远源效应有关。

英文摘要：

Based on analysis on regional geology, strata thickness, sedimentary characteristics and faulting intensity of Huimin sag,this paper studied the characteristics of structural activities and the depocenter migration patterns in different evolutionary periods of Huimin sag and explained their geodynamic mechanisms.New methods were proposed for delinea-tion of depocenters.There were two dynamic depocenters or subsidence centers in Huimin sag in the Cenozoic era.The depocenters and subsidence centers basically coincided with each other except for Es4 period.The depocenters had migra-ted to the southwest of Linyi,while the subsidence centers were still in the west of Zizhen during the Es4 period.The Es4 -Es3 periodwas an important transition period for the migration of subsidence centers which migrated mainly along the N-S direction.In contrast,the migration was mainly along the E-W direction during Ek-Es4 period and Es3 -Ed period.In the western part of the sag,the depocenters migrated in “S”-shaped trajectory,while in the eastern part,they migrated anticlockwise.Sag-controlling faults were mainly active during Ek and Es4 period,while subsag-controlling faults were predominant in Es3 -Ed period.Both the sag-controlling and subsag-controlling faults were controlled by the NNW-trending extension structure and the right lateral strike-slip of Lanliao fault and Tanlu fault.And it was related to mantle convection caused by the velocity and angle changes of the Pacific plate subducting to the Eurasian plate and the collision of India-Eurasia plate.
