Abstract:
Continuous late Neogene planktonic foraminiferal records have been studied in the deep-sea cores of DSDP Sites 173, 310, and 296 across mid-latitudes of the North Pacific. These three sites have been correlated on the basis of planktonic foraminiferal events and major paleoclimatic/paleoceanographic intervals and tied to diatom, radiolarian, and nannofossil datum levels, and paleomagnetic and isotopic stratigraphy. Ten planktonic foraminiferal datum levels have been recognized within these Pliocene to Pleistocene sections; two of these are recognizable within the Pleistocene and eight within the Pliocene. Six planktonic foraminiferal zones are proposed which combined with the foraminiferal datum levels provide a high resolution biostratigraphic correlation for the mid-latitudes of the North Pacific.
