Abstract

"A method is proposed for presenting paleomagnetic data by means of isoclines on paleomagnetic maps. These maps offer a more detailed picture of ancient magnetic fields than is given by a single virtual pole position. The isoclines of these maps restore the original connection between the continental forms and their ancient magnetic--and geographic--latitude. This is of importance particularly when we want to investigate the mutual relative positions of different continents or tectonic units of the past: from the maps we can easily see where continentalcoasts were opposite one another, and what rotations and translations have occurred since. Paleomagnetic data make the assumption of continental drift and polar wandering necessary; the data do not appear to be in conflict with themajor hypotheses on continental drift, which are based on geological, morphological, and climatological grounds."
