全新世旧黄河水下三角洲位于南黄海海州湾的南面、苏北岸外浅滩以北、东经122°15’以西的广大海区.水下三角洲形态明显,保存较为完好,是研究三角洲沉积的良好场所.长期以来,受到河口和海洋工作者的注视.1975年以来,海洋地质调查局在旧黄河水下三角洲地区进行了10×10公里网格的取样(表层、柱状和测深工作),本文在调查报告的基础上,参阅有关文献资料,对全新世旧黄河水下三角洲的地貌特征、成因、发育过程、沉积厚度以及演变等有关问题进行探讨.
The Holocene Old Yellow River Underwater Delta is located in the south of Haizhou Bay in the South Yellow Sea, north of the shores of the northern Jiangsu coast, and vast sea area west of 122 ° 15’E .. The underwater delta is well-formed and well preserved, which is a good place for studying delta sediments For a long time, the attention of estuarine and marine workers has been observed. Since 1975, the Bureau of Geological Survey has sampled 10 × 10 km grids (surface, columnar and sounding) in the Yellow River subaqueous delta, On the basis of the survey report, we refer to the related literature to discuss the geomorphic characteristics, genesis, development process, sedimentary thickness and evolution of underwater veins of the Old Yellow River in the Holocene.
