Figure 2. Correlation chart of Paleogene zonal schemes for foraminifers, calcareous nannofossils, radiolarians, and the geomagnetic polarity time scale of Cande and Kent (1995). Key to radiolarian zonal code numbers can be found in the text. Holes examined herein are correlated against nannofossil zones. Core and section numbers indicate level at which nannofossil boundaries occur. Hatching indicates uncertainty in placement of zonal boundary.
