Diatoms from Ocean Drilling Program Leg 184 Site 1143 in the southern South China Sea were analyzed for this paper. We found that diatoms are barren or scarce from 27.94 to 304.04 meters below seafloor. The intervals with age-diagnostic species indicate a middle Miocene age from 472.18 to 469.98 mcd, a late Miocene age or younger at 389.42 mcd, and a late Pliocene to Holocene age from 26.7 to 0.0 mcd.

Sediment depth is given in mcd.
