Applications of rock and mineral magnetism
The constitution of rock and mineral magnetism and its ‘applications’ or ‘connections’ are discussed in section 1.3. Some applications depend on the physical models of rock and mineral magnetism, and the extent to which rock and mineral magnetism research has provided experimental support for the models. The models essentially concern the acquisition and removal of weak field remanences, and form the physical basis for determinations of the direction and intensity of the ancient geomagnetic field, and the inferences which can be made from such a determination. The models also suggest methods by which the palaeomagnetic signal may be distinguished from ‘noise’. The models are applied in geological problems, such as the determination of emplacement temperatures, or in ‘magnetic granulometry’ with many areas of interest from technology to cosmology.
