The roundness and shape of clastic quartz-grains 0.25-0.315mm fractions from the East-China Sea Shelf sediments were investigated. Quartz- grains of most stations are characterized by great flatteness typical of that of sediments of large river under-water deltas. It is supposed that only some samples contain material from beach and shallow shelf sediments or aeolian. The supposed deltaic reworking sediment covers the shelf zone from the Changjiang River estuary to the shelf break.
