    摘要
  • 通过对内伶仃洋河口湾22个钻孔沉积物的高分辨14C测年、古生物鉴定、沉积物粒度及地球化学分析,开展了晚更新世地层划分,探讨了晚更新世以来的沉积演化过程。内伶仃洋河口湾地层被含花斑黏土层的风化层隔开,划分为上下2组,侵蚀面上下分别为全新统和上更新统地层。受晚更新世以来2次海侵的影响,内伶仃洋河口湾沉积演化分成了6个阶段,详细阐述了每个阶段的气候变化、海平面波动、沉积特征和沉积过程。
    According to the data of sediment gain size, element geochemistry and paleontology, as well as 14C dating in the Lingdingyang Estuary cores, we studied and discussed the sequence stratigraphy and sedimentary evolution in this paper. Using the spotted clay layer as the marker of erosion, the deposits since Pleistocene could be divided into two groups, the Pleistocene under the surface of erosion and the Holocene above the erosion surface. There are six stages of evolution including two transgressions. Each stage is elaborated in climate change, sea level fluctuations, sedimentary characteristics and sedimentary processes.
