Palaeomagnetism and diagenesis in sediments by Donald Harvey Tarling, Peter Turner, Geological Society of

By Donald Harvey Tarling, Peter Turner, Geological Society of London

This e-book incorporates a co-ordinated sequence of papers contemplating how chemical adjustments in sediments, as they acquire and lithify, have an effect on their magnetization and the way such adjustments should be monitored by means of learning their magnetic homes. it truly is specifically suitable to sedimentologists, rather these in exploration for hydrocarbons and sediment hosted fabrics, in addition to for geophysists utilizing the magnetization of sediments.

Intermediate remanence component Youngest remanence component Fig. 12. The debris flow test. This provides slowly reoriented slump blocks that may record components of the geomagnetic field in different orientations within the sample, if the orientation changes rate at a similar pace to viscous remagnetization. This is superficially comparable with the conglomerate test of traditional palaeomagnetism (Tarling 1983), but an important difference exists. The conglomerate test represents one discrete reorientation of material that may, or may not, remagnetize after reorientation (Fig.
