我国东海大陆架沉积类型分布状况,经过有关部门和单位的多次海洋地质调查,已获得了丰富的资料和成果。秦蕴珊等同志根据沉积物的中位直径(Md),将东海沉积物大体分成三带:第一带是近陆浅水区的细粒沉积物带;第二带是外陆架的粗粒沉积物带;第三带是大陆坡细粒沉积物带。他们认为这种分布是与东海大陆架所经历的海陆变迁有关,并详尽
The distribution of sediment types in the continental shelf of China’s East China Sea has obtained abundant data and achievements after many marine geological surveys by relevant departments and units. According to the median diameter (Md) of sediments, Qin Yun-shan and other comrades generally divide the sediments in the East China Sea into three zones: the first zone is a fine-grained sedimentary zone in the shallow water near inland and the second zone is the coarse-grained sediment zone ; The third zone is continental fine sediment zone. They consider this distribution to be related to the changes in the land and sea experienced by the continental shelf in the East China Sea, and they are exhaustive
