摘要: 南黄海北部坳陷是在印支期前陆盆地基底上发育的白垩纪—新生代大型伸展盆地。笔者系统总结了国内外学者南黄海北部坳陷周缘大地构造学研究、盆地内构造变形—陆相层序充填研究近年来的研究成果,对比了中韩两国学者对于北部坳陷的陆相层序划分方案的异同点,列举了目前研究的薄弱点,提出了一些亟待解决的问题。此研究对于东亚陆缘断陷盆地群地球动力学机制分析、扬子—华北碰撞造山带垮塌研究以及南黄海油气勘探突破均有重要的科学和经济意义。Abstract: The northern depression of the South Yellow Sea is a large Cretaceous-Cenozoic rift basin developed on the basis of a foreland basin by Indosinian orogeny. A number of research work, including both domestic and abroad, have been devoted to the tectonics of the South Yellow Sea and the stratigraphic sequences and deformation-infilling process of the depression. In this paper, we summarized the main achievements of previous studies, and compared the similarities and differences of the stratigraphic classification system between the Chinese and South Korean scholars. Weakness of the present study is cited and problems, which need to be solved urgently, were raised. The research work will help us better understand the dynamic mechanism of rift basins in the East Asia and collapsing mechanism of the Yangtze-North China orogenic belt. Strategically, it is of significance to break the deadlock in oil and gas exploration in the South Yellow Sea.
