Polar Movement Relative to Australia

Abstract

During Upper Proterozoic times the mean geomagnetic pole seems to have been situated near Australia. By the Cambrian it appears to have moved to what is nowadays the region of South Africa passing southwards into the Southern Ocean by Silurian and early Devonian times. in the Upper Carboniferous and Permian the pole lay in the Tasman Sea and Australia was once again in a high geomagnetic latitude. Later the pole moved slowly southwards, reaching the present geographic pole towards the end of the Tertiary. Copyright © 1958, Wiley Blackwell. All rights reserved
