Abstract

Three independent lines of research (by fauna, sediment facies, and remanent magnetism) have demonstrated the existence of a continental ice sheet over 4000 km of North Africa during the Ordovician and Silurian. The trace of this pole leads eventually to the present South Pole, although its paleomagnetic indications for Africa are properly described as “north.” Due to multiple magnetic reversals through time, confusion may result, and to avoid that situation, the writer proposes that the historic destiny of a given pole may be established if we call this “southern” one the “Gondwana Pole” and the “northern” one the “Pacific Pole.”
