Revised calibration of the geomagnetic polarity timescale for the Late Cretaceous and Cenozoic
Scripps Institution of Oceanography, La Jolla, California
Lamont-Doherty Earth Observatory of Columbia University, Palisades, New York
Recently reported radioisotopic dates and magnetic anomaly spacings have made it evident that modification is required for the age calibrations for the geomagnetic polarity timescale of Cande and Kent (1992) at the Cretaceous/Paleogene boundary and in the Pliocene. An adjusted geomagnetic reversal chronology for the Late Cretaceous and Cenozoic is presented that is consistent with astrochronology in the Pleistocene and Pliocene and with a new timescale for the Mesozoic.
