It has been found that the geomagnetic poles deduced from worldwide paleomagnetic data deviate systematically from the present rotation axis. Studies conducted with the aim to provide explanations for this phenomenon, in most cases, did not take plate motions into account. This must be done if the analysis is to be extrapolated back in time beyond 7 Ma. If hotspots are assumed to be stationary in the mantle as well as with respect to each other, they offer a reference framework against which plate motions can be viewed. In the present investigation, a plate motion model incorporating such a fixed hotspot framework is employed to remove the effect of plate motion on the positions of Cenozoic and Mesozoic paleomagnetic poles. The paleopoles are grouped and averaged. The investigation indicates that the pole has moved 22 deg + or 10 deg in the past 180 m.y.
