The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.

The sand dunes analyses data have shown they mainly consist of well sorted, symmetry skewness and find sands, and the kurtosis peak is narrow or very narrow. There are abundant impacts of mechanic process on the surface of quartz grains. The traces of eolian process often superpose on the traces stamped by river and beach processes. The dish--shaped concavities and mechanic pits are the most common surface textures, but the barchan concavities and curved grain edges are indicated the marks by eolian environment. The heavy minerals assemblages of coastal dunes are dominated by relatively high specific gravity which have stable chemical properity suggesting the mordern high dynamic environments of coast area. The depositional structures of coastal dunes are typified by corss--bed sets composed of steep foreset laminates and gentle windward dipping sets. It also contains some shell fragments and strong worn foraminiferal tests that are impossibly found in inland desert. On the other hand, the sandy deposits of the continental shelf of East China Sea are with wide range of grains, and the depositional pattens are quite complicated.
