Palaeomagnetic results and late Precambrian glaciations

A combined late Precambrian to early Palaeozoic polar wander path, which differs from that previously proposed for Africa and South America, is derived for Gondwanaland. It suggests that Gondwanaland existed at least 750 Myr ago. The widespread distribution of late Precambrian glaciations can be explained in terms of this polar migration. It is predicted that the late Precambrian and Cambrian part of the North American polar wander path may be more complicated than previously supposed.
