利用钻孔、柱状样及浅地层剖面仪等对长江水下三角洲进行了调查研究。结果表明,三角洲全新统的发育可分为全新世早、中、晚期沉积;自河口向海有三角洲前缘相、前三角洲沉积相、三角洲-陆架过渡相三个相带;全新世长江水下三角洲的垂直相序,覆盖在下伏浅海相之上,向上依次为前三角洲相和三角洲前缘相。
The Yangtze River subaqueous delta was investigated by means of drilling, columnar and shallow stratigraphic profile. The results show that the development of the deltaic Holocene can be divided into the Early, Middle and Late Holocene sediments. There are three facies of delta front facies, delta front sedimentary facies and delta-shelf transition facies from the estuary to the sea. During the Holocene, The vertical phase sequence of the delta covers the underlying shallow marine facies, followed by the front delta and the delta front.
