Paleomagnetic record from glacial varves in Alto Río Mayo, Patagonia, Argentina
Paleomagnetic study of a 3-m thick sequence containing 302 glacial varves outcropping in Alto Rio Mayo valley shows strong intensities, a declination shifting gradually to the west and an increasing negative inclination. Virtual geomagnetic pole positions reveal a migration of the geomagnetic pole f...
