High-resolution delta (super 13) C records are presented for the Miocene benthic foraminifers Cibicidoides wuellerstorfi and C. kullenbergi (24-5 Ma) and the planktonic foraminifer Globigerinoides sacculifer (18-5 Ma) from ODP Site 1148A (18 degrees 50.17'N, 116 degrees 33.93'E, water depth 3308.3 m) in the northern South China Sea. The general pattern of parallel benthic and planktonic delta (super 13) C shows a decreasing trend in delta (super 13) C values from the early-middle Miocene to the middle-late Miocene. Two distinct delta (super 13) C positive excursions at 23.1-22.2 and 17.3-13.6 Ma and two negative excursions at 10.2-9.4 and 6.9-6.2 Ma have been recognized. All these events are cosmopolitan, providing good data for the stratigraphic correlation of the South China Sea with the world's oceans as well as for studying changes in the global carbon reservoir and the corresponding climate.
