Abstract
Two sites were drilled in the Celebes Sea as part of Ocean Drilling Program Leg 124; Site 767 and Site 770. Radiolarians are preserved in Paleogene pelagic claystones with minor occurrences in certain Neogene successions. The brown clays that immediately overlie basalt at both sites contain radiolarians of the late middle Eocene Podocyrtis chalara Zone. Late Eocene radiolarians are not found, due to dissolution and probable hiatus. The Oligocene is represented by the Theocyrtis tuberosa and Dorcadospyris ateuchus Zones. Oligocene sediments are strongly dominated by abundant and diverse radiolarians of the TristylospyrislDorcadospyris lineage. Preservation of Paleogene radiolarian assemblages ranges from good to very poor. Late Miocene radiolarians of the Didymocyrtis antepenultima Zone are found only in Site 770. Other Neogene sediments are barren of radiolarian remains, with the exception of latest Pleistocene and Holocene sediments.
