This interpretation of paleomagnetic data is consistent with the suggestion that the main copper mineralization in this region is Jurassic (Li et al., 2009). Implications to Future Study Paleomagnetism (occasionally palaeomagnetism ) is the study of magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called paleomagnetists.

WebPaleomagnetism is a field of geological study that focuses on the magnetic signatures of rocks that capture the magnetic fields of the Earth at the time that they form. This … Webdetailed paleomagnetic and geochronological studies, geologists have discovered that the polarity of Earth’s magnetic field has periodically reversed, meaning that the north magnetic pole becomes the south magnetic pole and vice versa. The sequence of reversals occurring in the past several million years has been dated with the use of radiometric

WebApr 7, 2024 · The paleomagnetic pole for the MOB is located at 30.5°N/14.6°E (A 95 = 7.4°) at ca. 314 Ma. Combining our new results with published late Paleozoic paleomagnetic poles for the MOB and TVB suggests that the two blocks were distant from each other during the Middle Devonian and merged into a single TVB–MOB by ca. 315 Ma.
