WebCrustal magnetic anomalies rarely mimic the topography of the top basement, whereas gravity anomalies often do. There are several reasons for this. The magnetic susceptibility of crustal rocks varies between 10-4 and 10-1 3, meaning that large magnetic anomalies can be generated by deep as well as by shallow rock units. An example is the deep ... WebPalaeomagnetism is a relative dating tool that can be applicable for dating moraines or sediments that predate the last glacial cycle. Palaeomagnetism is based on changes in the Earth’s magnetic field as is preserved in rocks and sediments. The Earth’s magnetic field is dipolar; it possesses two poles (north and south).
