摘要

Based on the 5 600 km shallow seismic profile acquired in western South Yellow Sea recently, the authors distinguished and interpreted the stratigraphic sequences, and following conclusions are made: 1) the strata of South Yellow Sea since Early Pleistocene are divided into fourteen seismic units, and composed of six seismic sequences, representing six transgressive-regressive cycles, and the strata developed during oxygen-isotope stage 5 widespread mostly； 2) the study area can be divided into six deposit zones by Holocene strata thickness； 3) During oxygen-isotope stage 6 to 2, three paleo-channel stages are found in the area; 4) Paleo-Yangtze River flowed into paleo-Yellow Sea in Early Quaternary, and paleo-Yellow River flowed into paleo-Yellow Sea in mid-late Late Quaternary; 5) the early delta developed during high sea-level warm climate was large, and late delta developed when sea-level lowered was small; and 6) during transgression between late Pleistocene and early Holocene, paleo river-mouth sandbars and buried tidal creeks were developed.
