It is well-known that magnetic field analysis, in general, is more complex than gravity or thermal radiation. The dipole nature of the magnetic field, magnetic variability of the geological medium, and numerous magnetic field reversals cause it. Paleomagnetic investigation assists us in obtaining some "stamps" of past geomagnetic field configurations. Paleomagnetic research has revealed information about past (from hundreds of years to hundreds of millions of years ago) magnetic field changes, which reflects actual geological, archaeological, and environmental events of that time. Some geodynamic and tectonic information derived from the paleomagnetic field analysis cannot be received by any other geophysical or geological method. Paleomagnetic analyses are applied in various branches: geodynamics and tectonics, archaeology and environmental investigations, geological-geophysical mapping, searching economic deposits, and even forensic studies. Integration of paleomagnetic studies with radiometric dating, other geophysical methods, and different geological tools strongly increases the results' reliability. Therefore, any practical examples of paleomagnetic investigations are welcome in this Issue.
