Abstract

The arrangements of the Gondwanic continents for the Palaeozoic and the Mesozoic-Cenozoic transition are given. For the Palaeozoic the available palaeomagnetic data indicate that the palaeogeographic positions for South America, Africa and Australia in the Gondwana super continent are fixed relative to one another. The positions deduced for India from palaeomagnetic data and Antarctica from sea-floor spreading data are tentative. The obtained reconstruction of Gondwanaland is in good agreement with that given by DuToit. For the Mesozoic-Cenozoic transition the combination of palaomagnetic data and results from sea-floor spreading help us to determine a tentative distribution of the Gondwanic continents. The result is in agreement with geological and morphological evidences. A discussion of the chronological order of the drift episodes that caused the fragmentation of Gondwanaland is given.
