The late Quaternary paleoceanography and paleoenvironment in the Okinawa Trough, East China Sea, have been well reconstructed over the last decade, while in contrast the provenance of terrigenous sediments that have accumulated there remains enigmatic. In this study, rare earth elements (REE) were used to investigate provenance changes in sediments from Core DGKS9604, taken from the middle Okinawa Trough. Discrimination plots based on REE fractionation parameters suggest that the cored sediments have variable provenances over the last 30 ka, with the lower part (ca. 31-8.2 ka) ultimately originating mostly from the Changjiang (Yangtze River) and the upper part (7.1-0 ka) primarily from Taiwan. During the Last Glacial Maximum and early deglacial period, sea... |
