S.C. Cande, D.V. Kent, "A new geomagnetic polarity time scale for the late Cretaceous and Cenozoic," Journal of Geophysical Research, 97:3917-51,1992.
Steven C. Cande (Scripps Institution of Oceanography, University of California, San Diego): RThe geomagnetic polarity time scale is a cornerstone of the geosciences, providing the means for precise global correlation and the chronological framework for all modern time scales. The first geomagnetic polarity time scale that covered the entire Cenozoic era was constructed in the early days of the plate tectonic revolution in the late 1960s from a few carefully selected marine magnetic profiles (J. Heirtzler et al., J. Geophys. Res., 73:2119-36, 1968). This time scale not only was extremely valuable but also proved to be very durable. Although there have been many revisions to the time scale since 1968, they involved--for the most part--applying new calibration points to the magnetic anomaly spacings determined in the original time scale.
