Paleomagnetic stripes definition

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. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. 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 … See more As early as the 18th century, it was noticed that compass needles deviated near strongly magnetized outcrops.

WebA magnetometer towed above (near bottom, sea surface, or airborne) the seafloor will record positive (high) or negative (low) magnetic anomalies when over crust magnetized in the normal or reversed direction. The ridge crest is analogous to “twin-headed tape recorder”, recording the Earth's magnetic history. [11] WebThe pattern of magnetic stripes is actually called the "paleomagnetic anomaly pattern."
