Scope of the work - Palaeomagnetism is the study of the direction of ancient or 'fossil' magnetization of rocks. If the measured direction in a rock sample is the direction acquired in the earth's magnetic field at the time of formation, defined as the primary (0) direction, and if the age and orientation of the rock is known, the result may be used to study the magnetic field at that time. To do this it is necessary to provide evidence for supposing that the direction obtained is primary,...[Show more]
