Abstract

Drilling recovered an almost complete Cenozoic sequence at Site 762. Sediments at this site contain abundant, diverse, and generally well-preserved calcareous nannofossils. The continuity of the stratigraphic sequence, preservation of the taxa, and availability of magnetostratigraphy offered an opportunity to construct a first-order biomagnetochronologic history for late Miocene-Quaternary calcareous nannofossils at Site 762. Magnetochronologically dated FADs/LADs for 23 different nannofossils are given in this study. FADs or LADs for five of these species (Discoaster blackstockae, D. calcaris, Rhabdosphaera claviger, R. longistylis and R. procera) have never been presented before. In addition, a LAD for Ceratolithus rugosus is new. -from Authors
