Paleomagnetism theory of plate tectonics

Paleomagnetism (occasionally palaeomagnetism ) is the study of magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called paleomagnetists. Certain magnetic minerals in rocks can record the direction and intensity of Earth's magnetic field at the time they formed.

WebFred Vine and Drummond Matthews made a significant contribution to the development of plate tectonics theory in 1963, when their paper, 'Magnetic anomalies over ocean ridges' was published. It explained the first scientific test for sea floor spreading. WebEvidence from paleomagnetism led to the revival of the continental drift hypothesis and its transformation into the modern theory of plate tectonics. Apparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomalies did the same for seafloor spreading .

WebSep 27, 2024 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Convection currents carry heat from the lower … WebIn accordance with plate tectonic theory, Earth ’ s crust and upper mantle, which together constitute the lithosphere, consists of about 20 large plates that are about 60 mi (100 km) thick and thousands of miles wide. These plates move back and forth on top of a lower layer of material known as the asthenosphere.
