Since the development of the first comprehensive Cenozoic geomagnetic
polarity time scale in 1968, at least 11 additional time scales have b
een produced, potentially leading to confusion when comparing geologic
studies using different time scales. This compilation correlates 12 d
ifferent time scales published from 1968 to 1995, graphically and in t
abular form, in order to enable geoscientists to compare studies dated
on the basis of different time scales. The table and supporting docum
ents are stored electronically on-line at the World Data Center-A for
Paleoclimatology (National Oceanographic and Atmospheric Administratio
n/National Geophysical Data Center).
