摘要
以构造层序学、层序地层学理论为指导,建立了济阳坳陷第三系构造层序体系,细致分析了每个构造层序的识别标志、层序地层学特征及构造特征,首次提出济阳坳陷下第三系构造层序经历了孔店构造层序转型期、沙河街断陷发展期、东营末期构造反转期三个演化阶段.深化了济阳坳陷构造演化规律研究,为断陷盆地研究的深入提供了新的思路.
In this paper, following the theory of tectonic sequence and sequence stratigraphy, I build up the tectonic sequence of Tertiary in Jiyang Depression, analyze the identifying characteristics, sequence stratigraphic and tectonic characters of each tectonic sequence, propose that this series of tectonic sequences experienced three evolving phases, i.e., tectonic sequence transition phase of Kongdian, developing phase of Shahejie Depression and the latest tectonic inversion phase of Dongying. Furthermore, I will carry out the study in the tectonic evolving rules of Jiyang Depression, and hence provide new ideas for the further research.
