Scientific paper

This paper presents possible thermoviscous remanent magnetization models of the oceanic crust and upper mantle, determined on the basis of a typical thermal evolution model of the oceanic lithosphere, which give rise to magnetic anomalies similar to those observed at sea level and at Magsat altitude. It is found that viscous magnetization acquired within a given polarity is not removed by that acquired in the next polarity period. Oceanic layer 2A is magnetized uniformly with sharp and vertical boundaries between normally and reversely magnetized zones, similar to that of the standard model. The models predict that anomaly 33/34 measured at sea level, and the anomaly associated with the Cretaceous quiet period measured at Magsat altitude, will be skewed. To produce the observed skewness of both marine and Magsat magnetic anomalies, it is necessary to have a magnetic lower crust and upper mantle, with maximum possible magnetizations of at least 30 and 20 percent of that of layer 2A, respectively.
