摘 要: 秦皇岛柳江盆地发育的地层在华北地台上具有代表性,露头出露完整。为了厘清秦皇岛柳江盆地层序发育、演化及分布规律,为柳江盆地的层序地层学研究提供地质基础,本文基于Vail层序地层学理论,利用野外露头、地层剖面等地质资料,对研究区进行了岩石类型总结、层序划分以及地层特征分析研究,开展了层序界面识别、层序单元划分和层序地层特征研究,以期为华北地台的演化研究提供地质参考。
关 键 词: 地质学;地层学;层序界面;岩性;构造运动;柳江盆地

Abstract: The stratigraphy developed in the Liujiang basin of Qinhuangdao is representative of the north China Plateau, and the outcrops are complete. For the sake of clarity the development, evolution, and distribution of stratigraphic sequences in the Liujiang basin of Qinhuangdao, and to provide a geological basis for the study of stratigraphy in the Liujiang basin, this paper summarizes the rock types, delineation of the lithofacies and stratigraphic characterization of the study area based on the theory of Vail lithostratigraphy, and utilizes the geological data of field outcrops and stratigraphic profiles. We conduct the research on the recognition of lithostratigraphic interfaces, the delineation of lithofacies, and the study of lithofacies characterization in the study area, with the aim of providing geological references for the study of the north China Plateau’s evolution.
Key words: geology; stratigraphy; sequence boundary; lithologic map; tectogenesis; Liujiang basin
