Provenance Study of Core DGKS9617 in the East China Sea

Piston Core DGKS9617, which is located in northern part of the East China Sea, is divided into two sedimentary facies: tidal shallow marine facies (55 851cm), in which tidal current played an important role in the sedimentation of this part, and shallow marine facies (0 55cm). Although the lower and the upper part has different sedimentary environment, the provenance of the whole core does not change. The character of heavy mineral assemblage, the results of discrimination function of Fe, Mn, V, Cr, Ni, Cu, Zn, carbonate analysis and Ba Sr Zn ternary diagram consistently show that the mineral and geochemical characteristics of Core DGKS9617 are similar to the Changjiang River sediment, implying that its sediment is mainly provided by the Changjiang River.
