Paleomagnetism (occasionally palaeomagnetism) is the study of prehistoric Earth's magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called paleomagnetists.
The meaning of PALEOMAGNETISM is the intensity and direction of residual magnetization in ancient rocks.
The fixed orientation of a rock's magnetic minerals as originally aligned at the time of the rock's formation. Paleomagnetism is usually the result of thermoremanent magnetization (magnetization that occurs in igneous rocks as they cool).
Paleomagnetism refers to the study of the ancient magnetism of rocks, specifically their location relative to the ancient North Pole and other rocks, through the analysis of the permanent magnetism of ferromagnetic minerals.
1 sty 2014 · Paleomagnetism is the study of the Earth’s magnetic field in past times. A permanent record of the ancient magnetic field is recorded by certain ferromagnetic minerals formed in rocks either as they form, and/or when they are subjected to later geological events.
28 gru 2022 · Definition. Paleomagnetism is the record of the Earth’s past magnetic field preserved in rocks. The orientation of the magnetic field, retained in ferromagnetic minerals (Fe-Ti oxides and sulfides), mirrors the Earth’s magnetic field at the time the minerals passed through their Curie point (i.e., the temperature at which certain magnetic ...
