Palaeomagnetic and palaeoclimatological aspects of polar wandering
Abstract
This paper contains a summary of all the published palaeomagnetic observations from rocks of Pre-Tertiary age. Evidence is produced which shows that the ancient latitude deduced from the palaeomagnetic observations in several regions of the world, is similar to the latitude indicated for these same regions by palaeoclimatology. Thus it is reasonable to suppose that the magnetic and rotational axes of the Earth have approximately coincided since the Palaeozoic, as they are known to have done during the past 20 million years. On the basis of this assumption two further points are made:
1) In Pre-Tertiary times the pole was a great distance away from the present position, but the pole positions given by data from Pre-Tertiary rocks from four continents do not agree one with another.- Publication:
