Magnetic mineralogy is the study of the magnetic properties of minerals. The contribution of a mineral to the total magnetism of a rock depends strongly on the type of magnetic order or disorder. Magnetically disordered minerals (diamagnets and paramagnets) contribute a weak magnetism and have no remanence. The more important minerals for rock magnetism are the minerals that can be magnetically ordered, at least at some temperatures. These are the ferrom… WebMagnetic minerals deposited in sedimentary layers reflect the provenance of the sediments. For the continental shelf offshore Norway, Mørk, McEnroe and Olesen (2002) documented that the magnetic susceptibility and remanence are generally small, and few sands and shales were found to have high values. oraltek immunotherapy
