Secular variation magnetostratigraphy,urement techniques which have been found useful in investigating lake sediments and presents type palaeomagnetic secular variation records of both declination and inclination, from seven regions of the world. These patterns of secular change can be used as master curves for dating newly acquired palaeomagnetic records.

The majority of magnetic studies of natural samples have thus been carried out by palaeomagnetists investigating natural remanent magnetisations. These studies have involved

For older records of the geomagnetic field and its changes with time we must turn away from historical documents to the study of the fossil magnetism in the Earth’s

A History of Rome through the Fifth Century has improved dramatically. Advances have included increases in sensitivity, speed of measurement, portability, availability and simplicity of operation. Magnetic susceptibility equipment is now commercially available at reasonable cost largely owing to the technology developed for the amateur metal

Whether we are studying the lithosphere, hydrosphere or atmosphere, or the cycles which involve the transfer of material between them, the movement of solid particles in some form or other is of major importance.

Following Le Borgne (1955), several Western and Russian authors have studied the mechanisms whereby magnetic susceptibility (4.4) is often ‘enhanced’ in su
