关于渤海湾西部的现代沉积,前人已做了大量调查研究工作。本文通过对1983年该海区的调查资料和表层样、柱状样的粒度、重矿物及粘土矿物分析,讨论了本海区的现代沉积特征。 渤海湾沿岸几乎全是第四纪松散沉积物,海岸为典型的淤泥质平原海岸。渤海湾西部海域的现代沉积物主要来源于陆源碎屑物。沉积物的分布格局与沿岸入海河流的性质、海洋动力作用和海底地形密切相关。
Regarding the modern sedimentation in the west of Bohai Bay, many people have done a lot of investigations and studies. This article discusses the modern depositional features of the sea area based on the 1983 survey data and surface samples, columnar grain sizes, heavy minerals and clay minerals. The coasts of the Bohai Bay are almost all Quaternary loose sediments, and the coast is a typical silt plains coast. Modern sediments in the western Bohai Bay are mainly derived from terrigenous debris. The distribution pattern of sediments is closely related to the nature of coastal rivers and rivers, the dynamic of ocean and the seafloor topography.
