Magnetization of Atlantic Seamounts
Abstract:It is possible to infer the direction of magnetization in a seamount from its shape and the associated magnetic anomaly. Such a direction is equivalent to a paleomagnetic direction established by the standard methods of measuring the direction of magnetization of oriented rock samples. The result of applying this analysis to some seamounts in the Gulf of Guinea is described. By calculating the paleomagnetic pole position from the direction of magnetization in the seamounts, and comparing it with African paleomagnetic pole positions, it is shown that the concept of plate tectonics is obeyed, in that there seems to have been no relative motion between Africa and the Gulf of Guinea since the latter was formed during the opening of the Atlantic Ocean. Likewise, previously published paleomagnetic results from the Kelvin group of seamounts agree with North American paleomagnetic results.
