Evidence on the stability of remanence is examined in 50 sites in red sandstones and 2 sites in basaltic lavas ranging in age from PreCambrian to Quaternary. It is concluded that the stability is variable although the tests often yield contradictory results. The data are too few for full interpretations in terms of polar wandering or tectonic movements, but it is found that the majority of sites are normally magnetized and of low inclination of remanence.
