Abstract

A reappraisal of Paleozoic paleomagnetic data from Australia is given. An alternative apparent polar wander path is suggested after adopting the reversed polarity option for pre-Devonian poles. Hitherto 'anomalous' Siluro-Devonian pole positions thus appear as conformable. This new polar path is compared to Paleozoic paleomagnetic data from other Gondwana continents which are seen to support the Australian path. The new path, in turn, supports the interpretation of Paleozoic glacial deposits being indicative of high latitudes and the transgression of an ice cap.It is suggested speculatively that systematic polar wandering of the type described here may indicate a systematic pattern of plate motions and consequently, systematic tectonic processes.
