南黄海北部盆地张裂阶段经历4期拉张。同期半地堑具多种组合形式,它们控制沉积物分布,导致各凹陷具不同沉降史。不同期半地堑的叠合反映盆地在时序上的演化特征。盆地拉张应力曾发生旋转,拉张速率从慢到快再到慢。阜宁期拉张作用最强烈,拉张方间近N-S向,是盆地的全面形成时期。 The southern Yellow Sea basin in the northern part of Zhang Zhang experienced four stages of tension. In the same period, there are various combinations of semi-graben, which control the distribution of sediments, leading to different subsidence history of each sag. The superimposition of the semi-graben in different periods reflects the evolutional characteristics of the basin in time series. Pull tension has occurred in the basin rotation, stretching speed from slow to fast to slow. The most intense stretch of the Funing period, stretching the near N-S direction, is the basin of the formation of a comprehensive period.
