黄海三大盆地的构造演化

中国科学院海洋研究所 青岛 266071
摘要:
70年代末至80年代中期，中国地质矿产部和中国科学院所属单位对黄海进行了大量地球物理调查和钻探。根据多道反射地震资料，浅地层剖面、重磁资料和钻探结果对黄海三大构造盆地进行地质构造学分析研究。结果表明，黄海地区三大盆地自北往南形成时代逐渐变新，构造活动性逐渐增强。

TECTONIC EVOLUTION OF THREE STRUCTURAL BASINS IN THE YELLOW SEA

Abstract:
The Yellow Sea developed three (from north to south) large structural basins, the North Yellow Sea basin, the northern basin of the South Yellow Sea and the southern basin of the South Yellow Sea. From since l970s seismic data, submarine profile, gravity, geomagnetism and drilling investigations, it is known .that the structral features of the three basins are characterized by gradual development from north to south: (1) Basements of basin become newer and newer southward; (2) Forming time of basins is later and later southward; (3) The sedimentary center gradually shifts southward; (4) Seismic activity strengthens from north to south. Back-arc extension is the dynamic mechanism of the three Yellow Sea basins. Their tectonic evolution is mainly controlled by the subduction of the Philippine Plate but is also influenced by the activity of the Tanlu Fault.
Key words:  Crustal structure, Sedimentary basin, The Yellow Sea
