| 摘 要： | 南黄海盆地属于下扬子地块海域部分,是我国海相中—古生界发育最齐全,保存相对较完整的地区之一。该区具双层基底结构及复杂的深部构造体系,经历了多旋回的盆地成生、改造及叠加过程。海相中—古生界则经历了印支、燕山、喜山等构造运动的改造,以往由于缺少深部地震资料,无法对海相中—古生界进行构造区划。通过该区沉积盆地原型的分析,结合深部地震资料的解释划分了南黄海盆地海相中—古生界的构造格局。

| Abstract: | The South Yellow Sea Basin,as part of the Lower Yangzi Plate submerged under the sea,is one of areas in China with the most complete Mesozoic-Paleozoic deposits.After a complex history of polycyclic evolution,alteration and superimposition,this basin is characterized by a dual-basement structure and a complicated deep structural system.The marine Mesozoic-Paleozoic has experienced the strong transformations of the Indosinian orogeny,Yanshan movement and Himalayan movement.In the previous studies,the lack of deep seismic data made us impossible to delineate the tectonic framework of the marine Mesozoic-Paleozoic in details.In this article,the newly acquired deep seismic data are used to divide the tectonic units of the South Yellow Sea based on the prototypes of sedimentary Basin. |
