Measurement of the NRM of rocks,uced magnetization .. in the ambient geomagnetic (or laboratory) field ..where . is the volume susceptibility, assumed here to be isotropic. In palaeomagnetism it is the intensity and direction of .. that is of major interest and some aspects of its measurement are considered in this section.

Field and laboratory stability tests,ter the time of formation, which if not detected and removed prevent the direction of the primary magnetization, and thus the ancient field direction at the site, from being established. The possible origins of secondary NRM are viscous remanent magnetization (VRM), partial thermoremanent magnetizat

Presentation and treatment of data, After magnetic cleaning a well-defined mean primary NRM direction ideally remains which, with other site means from the same rock unit, can be interpreted through an overall formation mean direction in terms of polar wandering and/or plate movements.

Identification of magnetic minerals and carriers of NRM,gnificance of the NRM and of the rock’s magnetization history. If several magnetic minerals are present, only one of which is carrying a primary NRM, experiments designed to identify the latter should clearly involve the remanent magnetism only and not other properties, e.g. induced magnetization, t

The sampling of rocks for palaeomagnetism,al in which the rocks acquired their primary magnetization. The factors which have to be taken into account to achieve this are the nature of the Earth’s magnetic field and its variations, the time-depth relationship in a geological structure and the process by which the rock acquired its remanent magnetism.
