| 摘 要： | 晚更新世气候的冷暖交替引起全球海平面的下降与上升,在南黄海地层中,最直接的体现就是海陆交互式沉积层。利用最新的高分辨率浅地层剖面资料,对南黄海西部近海陆架晚更新世以来的地震地层进行了详细划分,探讨了晚更新世两个海进层序中古三角洲的划分及其地震相特征,认为晚更新世南黄海古三角洲可分为4个较大的期次。根据沉积物特征分析判断4期古三角洲均为古长江形成,各期三角洲相互叠置,范围、厚度及扩建方向均有不同,各期古长江三角洲与海平面变化有很好的对应关系。

| Abstract: | The alteration of climate in late Pleistocene caused global sea-level changes.Its direct reflection in the South Yellow Sea is sea-land interbedding facies.Up-to-date high resolution shallow seismic profile was used to analyse the post-late Pleistocene seismic strata in the west offshore continental shelf of the South Yellow Sea.The paleo deltas were then measured and the seismic characters were discussed.The current paper concludes that the paloe deltas can be divided into four large periods.Judging from s... |
