Sager, W.W. (1987). Late Eocene and Maastrichtian paleomagnetic poles for the Pacific Plate; implications for the validity of seamount paleomagnetic data. Tectonophysics 144(4): 301-314. doi: 10.1016/0040-1951(87)90298-8.

Mean paleomagnetic poles for the Pacific plate have been calculated for the Late Eocene (39 Ma) and the Maastrichtian (69 Ma). The former is located at 77.6 degrees N, 7.6 degrees E. the latter at 69.9 degrees N, 0.9 degrees E. Although these pole positions are little changed from previous calculations they are better constrained with additional data. Slightly less than half of the data are derived from the inversion of seamount magnetic fields providing an excellent opportunity to compare such data with other paleomagnetic data of the same age. As no significant systematic difference between the two types of data is evident, it is inferred that most seamount paleomagnetic data are probably useful indicators of the paleomagnetic field direction.
