Abstract

Abstract

The accumulation rate has been evaluated based on the dating data of 136 sediment cores taken from areas deeper than 100 m in the South China Sea since the last glaciation.The average annual deposit amount is 152.3 Mt/a during MIS (marine isotope stage) 1 and 215.2 Mt/a during MIS 2 respectively, which are mainly contributed by terrigenous sediments.The accumulation rate is the highest in southwestern continental slopes followed by northeastern area, and lower in other part of the South China Sea during both of the last glaciation and Holocene.Although the accumulation rate during MIS 2 is much higher than that during MIS 1 in most part of the South China Sea, it has opposite trends near the rapidly accumulated areas because of more active side and downslope transport.
