黄河海港附近上部4m沉积层序自下而上为:(1)1964年以前形成的河口沙坝沉积物;(2)1964～1972年形成的下三角洲平原(潮滩)和三角洲侧缘沉积物;(3)1972～1974年形成的决口扇和近河口分流河道充填沉积物;(4)1975～1984年分流河道废弃后形成的湖滩沉积物。这一层序显示平行海岸方向环境的垂向叠覆。这是黄河三角洲垂向序列的一个重要特征。
The upper 4m sedimentary sequence near the Yellow River seaport is bottom-up: (1) estuarine and barren sediments formed before 1964; (2) the lower delta plain (tidal flats) formed between 1964 and 1972 and delta sediments ; (3) Crepuscular sediments formed in the confluence of estuaries and estuaries from 1972 to 1974; and (4) Lake beach sediments formed after the distributary channel was abandoned from 1975 to 1984. This sequence shows the vertical stacking of the parallel coastal environment. This is an important feature of the vertical sequence in the Yellow River Delta.
