本文根据地质钻探资料的岩性特征和部分微体古生物的分析成果,指出闽江口外海滨段三角洲的发育存在着明显的沉积顺序。对于三角洲表层沉积物的粒度分析和粒度参数统计,获得了不同沉积环境下沉积物特征和沉积区的不同泥沙补给来源。
Based on the lithological characteristics of geological drilling data and the analysis results of some micro-organisms, it is pointed out that there is a clear sequence of sedimentation in the delta of the offshore section of Minjiang Estuary. For the particle size analysis and particle size statistics of surface sediments in Delta, different sources of sediment supply were obtained under different depositional environments and sediment characteristics.
