位于中国东部近海海域的南黄海盆地属于特征比较典型的中生代残余盆地。该盆地属于“断陷—坳陷”的复合型盆地,其构造演化以晋宁事件和印支—燕山事件为界,可划分为前扬子板块、稳定地台以及西太平洋活动陆缘三个演化阶段。文章从盆地所处的大地构造背景入手,主要阐述了盆地中生代的构造演化以及沉积地层特征,认为南黄海盆地在白垩纪沉积时期,古气候由干旱逐渐变潮湿,特别是在晚白垩世泰州组沉积时期,气候变潮湿,有利于湖泊和烃源岩的发育。中生代地层内褶皱和逆冲推覆构造发育普遍,沉积中心在这一时期可能发生迁移。
The southern Yellow Sea basin located in the offshore area of eastern China belongs to the typical Mesozoic remnant basin. The basin belongs to the compound basin of “rift-depression”. The tectonic evolution of the basin is divided into the three evolutions of the former Yangtze plate, the stable platform and the active continental margin in the western Pacific by the Jinning event and the Indosinian-Yanshan event stage. Beginning with the geotectonic background of the basin, the paper expounds the Mesozoic tectonic evolution and the characteristics of sedimentary strata in the basin. It is concluded that paleoclimate changed gradually from arid to damp during the Cretaceous sedimentation in the South Yellow Sea Basin, especially in the Late Cretaceous Taizhou Formation During the depositional period, the climate becomes humid and favorable to the development of lakes and source rocks. The fold and thrust nappe structures are generally developed in Mesozoic strata, and sedimentary centers may migrate during this period.
