EARLY PALEOZOIC EVENTS PALEOGEOGRAPHY Paleomagnetic data Paleomagnetic evidence provides information on the latitude at which the rocks formed. The orientation of the continent can be determined from the direction to the paleomagnetic pole, as recorded by bits of iron in the rock. Longitudes, however, cannot be determined (which accounts for some of the differences in the paleogeographic reconstructions).
