What is paleomagnetism and why is it important? - Studybuff

WebPaleomagnetism is the study of magnetism in ancient rocks. The phenomenon was first discovered by the French physicist Achilles Delesse (1817 – 1881) in 1849, who observed that certain magnetic minerals in rocks were aligned parallel to Earth ’ s magnetic field. WebFeb 14, 2024 · Paleomagnetism is the study of the fixed orientation of a rock's magnetic minerals as originally aligned at the time of the rock's formation (simply, old magnetism ).

Why Was Paleomagnetism So Important In Discovering Plate Tectonics

WebMore evidence was needed to support this theory, however. When scientist mapped out earthquake patterns around the world, they discovered that the location of earthquakes were associated with the locations of the subduction zones. This further provided evidence for plate tectonics. More evidence came when scientist examined the sea floor and ...
