WebFeb 10, 2024 · Paleomagnetism is the study of the record of the earth’s magnetic field with the help of magnetic fields recorded in rocks, sediment, or archaeological materials. The polarity of the Earth’s magnetic field and magnetic field reversals are thus detectable by studying the rocks of different ages.

WebA polarity reversal means that the magnetic North flips to where we know the South Pole is. At the mid-ocean ridge spreading axis, these flips in the direction of the Earth’s magnetic field are recorded in the magnetization of the lava.
