Summary

Paleomagnetic results from Africa have increased substantially in number since 1970 especially for the Precambrian. Noteworthy is the now very complete coverage of the Mesozoic, together with a good comparison between Madagascar and Africa which yields a paleoposition for Madagascar close to the east African coast. The Paleozoic is less well covered and much of the Karroo Supergroup remains to be sampled in detail. The Precambrian data is of very variable quality but it helps to define the apparent polar wander path with greater certainty than previously. Many gaps remain, however, and a much higher density of data will be required. Careful multi-component studies have begun to appear and these must play an increasingly important role in the future work.
