For geological times older than the age of the sea floor and for which it is possible to justifiably extrapolate specific supercontinent configurations, an appeal to paleomagnetism would seem the most appropriate approach to solve problems of continental distribution. In order to improve upon procedures whereby apparent polar wander paths are matched solely by inspection, an iterative technique has been developed which makes it possible to match paths on the surface of a sphere on an objective basis. The notion of a minimum combined path length from a comparison of two data sets is used to determine the optimal match-up. The technique is appropriate to cases where the only dating available for the points on each path is their relative chronology.
