The extreme linearity and continuity of oceanic magnetic anomalies and their symmetry about the axes of oceanic ridges suggests that variations in intensity and polarity of the geomagnetic field are recorded in the remanent magnetization of the igneous rocks as they form at the crest of a ridge and spread away from it at a steady rate. If the proposed magnetic time scale for the last four million years is combined with this model, computed anomaly profiles show remarkably good agreement with those observed, and deduced rates of spreading are in exact agreement with those needed to account for continental drift. Within the framework of ocean floor spreading, magnetic anomalies may indicate the nature of fracture zones and distinguish parts of the ridge system that are actively spreading.
