| 摘 要： | 黄河三角洲前缘粉砂分布于河口外中部,三角洲侧缘或分流间湾黏土质粉砂分布于三角洲前缘粉砂体的两侧。分流改道时新的分流河口大多分布在老叶瓣三角洲侧缘或分流间湾位置。这样,年轻的三角洲前缘粉砂覆盖在老三角洲侧缘或分流间湾黏土质粉砂之上,与此同时,年轻的三角洲侧缘或分流间湾黏土质粉砂覆盖在老三角洲前缘粉砂之上,形成规律性的叠覆层序。在观察钻孔岩心时,正确判断某一层的沉积环境,追踪其物质来历,即判断是从哪一条分流河道搬运来的物质形成的,该分流河道的活动年代就是该层形成的年代。

| Abstract: | The comprehensive analysis of historical geography and sedimentary geology can be applied for dating the sedimentary layers of this very young delta.The form of the subaqueous delta lobe is like a lens and the delta front silt is located at the middle off the river mouth and the delta lateral(interdistributary bay) clayey silt is distributed beside the delta front.Commonly the younger distributary channel mouth is located between two abandoned river mouths.The younger delta front silt overlays the older del... |
