WebPaleomagnetism. This chapter highlights the ways in which rocks become magnetized. It also interprets paleomagnetic results in terms of the theories of polar wandering, continental drift, and an expanding Earth. The chapter describes the salient characteristics and trends of the geomagnetic field during the period of direct observation. WebGeologists can measure the paleomagnetism of rocks at a site to reveal its record of ancient magnetic reversals. Every reversal looks the same in the rock record, so other …
