(Table 1) Ages of planktonic foraminiferal datums at Leg 94 Sites

The six Leg 94 sites have produced a unique data set from a north-south transect of sites, all with good paleomagnetic records, and all but one with above-average accumulation rates. We show that it is necessary to have high accumulation rates to obtain good quality magnetobiostratigraphies, and tha...

We show that it is necessary to have high accumulation rates to obtain good quality magnetobiostratigraphies, and that it is difficult to correlate geological sequences over distances of several hundred kilometers without independent age control. Using the paleomagnetically derived ages for species ranges, we show several examples of diachronic first and last appearance datums between the core sites. This has enabled us to test the existing zonal schemes for the Pliocene-Pleistocene and to identify new zonal markers.
