摘　　要：根据1996年"中－法合作东海计划"，在东海大陆架打钻一口，取一长196cm的岩芯。对该岩芯样品粒度分析结果和现场生物种属记录综合研究，表明此岩芯属浅海沉积，既有波浪多次往返搬运沉积的特点，又有河流砂沉积的特点。以74cm为界，上层为冰后期海进滨海相沉积，下层为晚更新世末冰期海退海相沉积。Based on the data of 196 centimeter core, which was obtained from the continental shelf of East China Sea during the course of the 'China France East China Sea Cooperation Plan'in 1996, the core, grain-size analysis, on-the-spot study on species and genus of the organism, and comprehensive study on the sedimentary record wereperformed in detail. The results indicate that the core belongs to shallow-sea factes deposit, with characteristics of repeated back-and-forth transportation by the wave. as well as that of fluvial sand deposit. I.ooking on 74 centimeters as boundary line the core can be divided into two parts:the upper section is transgressive-typed littoral fades deposit formed during post-glacial period, and the lower part belongs To regressive-typedsea-factes deposit formed during glacial Period at the end of Epipleistocene.
