Sedimentary Facies and Material Source of Core DGKS9617 in the East China Sea
A piston core DGKS9617, recovered from the northern part of the inner shelf of the East China Sea (ECS) is divided into two sedimentary facies: a tidal shallow marine facies (55-850 cm) and a shallow marine facies (0-55 cm). Although the sedimentary environments of its upper and lower parts are different, the provenance of the whole core does not change. The heavy mineral assemblage, the results of the discrimination function of Fe, Mn, V, Cr, Ni, Cu and Zn, the carbonate content and the Ba-Sr-Zn ternary diagram consistently show that the heavy mineral and geochemical characteristics of core DGKS9617 are similar to that of the Yangtze River sediments and that its sediment is mainly provided by the Yangtze River.
