Abstract
Abstract The results of experiments on the watering of different types of continental Quaternary sediments in the anomalous magnetic field show that it can cause strong changes in the direction of remanence. The direction of acquired post-depositional remanent magnetization is stable to thermal and alternating field (AF) demagnetization. These changes are not related to the chemical remagnetization and are probably caused by mechanical rotations of magnetic particles in the pore spaces. Post-depositional remagnetization, both in nature and after collection of sediment samples, can distort the palaeomagnetic record of geomagnetic excursions, events and polarity transitions, as well as altering the finestructure features, such as the palaeomagnetic record of secular variations.
