Publisher Summary This chapter focuses on the Late Cenozoic Paleomagnetic studies in Patagonia. Paleomagnetism is a geoscience that incorporates aspects of geomagnetism, rock magnetism, and geology. paleomagnetic studies have applications to a wide variety of geological problems. In paleogeographic studies, paleomagnetism is providing evidence about movement of large crustal blocks and localized rotation of smaller tectonic blocks. Also, paleomagnetism can be used for stratigraphic correlation and geochronological calibration of paleontological zonation. Paleomagnetic studies of Late Cenozoic rocks in Patagonia have been made from the early times of this discipline. So far an important number of studies have been carried out in Late Cenozoic basaltic lava flows, glaciolacustrine sediments, lake sediments, and sediments from archeological and paleontological locations. Paleomagnetic studies carried out in basalts have allowed determining the secular variation of the geomagnetic field, measured by the angular dispersion of the Virtual Geomagnetic Pole (VGP) around the Earth's rotation axis. |
