Abstract

Abstract

The most prominent cooling event of the Cenozoic earth surface during the long-term transition from a non-glaciated planet, or "green-house world", to a polar glaciated planet, or "ice-house world", is the earliest Oligocene glacial maximum (EOGM), immediately following the Eocene-Oligocene (E/O) boundary at about 33.7 Ma. This study analyzed benthic foraminiferal oxygen and carbon isotopes, carbonate content, coarse fraction, planktonic foraminiferal fragmentation, benthic foraminiferal percentage, and carbonate ooze grain size in samples from deep-water Site 1265, Ocean Drilling Program (ODP) Leg 208 on the Walvis Ridge, South Atlantic. The results show that the earliest Oligocene δ¹⁸O values represent the magnitude of continental ice sheets on east Antarctica and indicate a large decrease in both surface and deep water temperatures of worldwide oceans during the Eocene-Oligocene transition. Carbonate content, coarse fraction, planktonic foraminiferal fragmentation, benthic foraminiferal percentage and grain size of ODP Site 1265 indicate that carbonate content increases rapidly across the E/O boundary, reflecting the increasing of ocean paleo-productivity, the abrupt deepening in the carbonate compensation depth (CCD) and their impacts on faunas and carbonate deposition.
