Paleomagnetic definition

WebJun 28, 2024 · The paleomagnetic method makes it possible to quantitatively calculate large-scale horizontal displacements of tectonic blocks with an accuracy of about 500 km and determine the relative positions of various structural elements of the lithosphere in the past, thereby imposing a rather strict limit on paleotectonic reconstructions [ 3, 7 ]. WebPaleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.
