沉积过程和构造作用的关系研究历来都是地质工作者进行盆地分析的核心问题,层序地层学的提出与发展将该问题在现阶段已演变为结合构造演化发展,从三维空间整体解剖沉积过程的沉积体系研究,研究结果表明,构造作用是控制陆相断陷盆地沉积体系发育、展布及演化的主要因素之一。该文在岩心观察、野外露头、测井曲线识别及地震资料解释的基础上,将苏北盆地高邮凹陷马家嘴-联盟庄地区戴南组划分为湖泊、湖底扇、近岸水下扇和扇三角洲4种沉积体系,在结合马家嘴-联盟庄地区构造发展演化过程的基础上,分析得出研究区戴南组的沉积体系在纵、横向上受构造控制作用明显。
The research on the relationship between sedimentation process and tectonic function has always been the core issue of basin analysis by geological workers. The proposal and development of sequence stratigraphy has evolved into the development of tectonic evolution at this stage. From the overall anatomical deposition process in three-dimensional space The results show that tectonism is one of the main factors that control the development, distribution and evolution of sedimentary systems in continental rift basin. Based on core observation, outcrop of outcrops, logging curve identification and seismic data interpretation, the Dainan Formation in the Majiazui-Lianmengzhuang area in the Gaoyou Sag of the Subei Basin is divided into lakes, sublacustrine fans, nearshore subaqueous fans and Based on the tectonic evolution and evolution of the Majiazui-Unionman area, it is concluded that the depositional system of Dainan Formation in the study area is controlled by tectonics in both vertical and horizontal directions.
