Carbonate-rich sequences in the deep sea of the eastern South China Sea subbasin (IODP Hole U1431D) during the last 600 kyr

Here, we examined changes in carbonate preservation in a deep-sea record (Hole U1431D, 4240 m water depth) retrieved from the South China Sea (SCS) during the International Ocean Discovery Program (IODP) Expedition 349. To evaluate these changes, we applied a micropaleontological and geochemical multiproxy approach including, planktonic foraminifera (PF) total abundance, fragmentation (FI%) and dissolution (FDX) indexes, and total organic carbon...
