运用地震地层学方法 ,对 1996年中法合作自长江口至冲绳海槽获取的 5 6 0 0 km高分辨率电火花单道地震及部分多道地震资料进行全面判读研究 ,并与位于陆架中部的 DZQ4井岩性分析资料进行对比 ,划分出东海陆架研究区自中更新世以来 3类共 11个地震层组 ,对每个地震层组的顶、底边界、内部主要地震相特征进行了详细描述 ,对各地震层组主要沉积相和沉积环境进行了合理推测 ,并与氧同位素期和全球冰期进行对比。对研究区主要地震相进行了归纳 ,划分出 4大类共 13个亚类的地震相 ,不同地震相类型再现了不同地质时期的沉积环境 ,并对研究区 4期潮流沙脊、多处典型古河道和两处海底峡谷特征进行了描述 Based on the seismic stratigraphy method, the comprehensive interpretation of the 5,600 km high resolution EDM single channel seismograms obtained from the Sino-French cooperation from the Changjiang Estuary to the Okinawa Trough in 1996 and some multi-channel seismic data are carried out. DZQ4 well lithology analysis data to compare the classification of the East China Sea shelf from the Pleistocene since the Pleistocene, a total of 11 categories of three kinds of seismic layers, the top of each seismic group, the bottom boundary, the main seismic facies features were detailed Description, the main sedimentary facies and sedimentary environment of the various seismic strata were reasoned, and compared with the oxygen isotope and the global ice age. The major seismic facies in the study area are summarized, and the seismic facies of 13 sub-groups of four major types are divided. Different seismic facies reproduce the sedimentary environment in different geologic periods. Ancient river courses and two submarine canyons are described
