Webrock is an important target for paleomagnetic studies. The fi rst is that sedimentary rocks give a nearly conti-nuous record of the geomagnetic fi eld. This is critically important to paleomagnetic studies because it allows undisputed time averaging of the secular variation of the geomagnetic fi eld and the application of the geo- WebThis is known as a depositional remanent magnetization ( DRM) ( q.v. ). This is the essence of paleomagnetism that the rock will lock in a fossil record of the ancient (or paleo) magnetic field. The fossil magnetism naturally present in a rock is termed the natural remanent magnetization ( NRM) ( q.v. ).
