| They also undertake studies in reflection seismology, geomagnetism, paleomagnetism, geothermics, the Earth's gravitational field and marine sedimentology. |
| By the end of the 1960s the knowledge available, provided by bathymetrics, paleomagnetism and seismography in particular, was extensive. |
| So-called exotic terranes, geologic fragments that differ markedly in stratigraphy, paleomagnetism, and paleontology from adjoining continental crust, were accreted to the margin of the North American plate. |
| The most useful is paleomagnetism and the sub-discipline of archeomagnetism. |
| Nevertheless, the explosive development of rock magnetism and paleomagnetism after the war, in France most notably the work of Emile Thellier, could hardly fail to attract his attention. |
