WebPaleomagnetism is the study of Earth's magnetic field using Earth's rocks as records. These rocks can have magnetic properties that geologists study to record the history of the magnetic field. Rocks that contain minerals that respond to magnetic fields align with the magnetic field thereby preserving the position of the magnetic field.

WebFeb 14, 2024 · Paleomagnetism studies are fundamental to the theory of seafloor spreading. Seafloor Spreading Seafloor spreading is the processes associated with the formation of new areas of oceanic crust, which occurs through the upwelling of magma at mid-ocean ridges and its subsequent outward spreading movement on either side.
