At the Permian/Triassic boundary, terrestrial as well as marine life was seriously decimated. The drastic reduction was possibly due to a global event. In order to demonstrate this, sections at great distance from one another need to be correlated, which is a difficult task, especially between marine and land sections. One of the methods, which is independent of the environment, is magnetostratigraphic correlation. It was intended to apply this method for precise dating to Permian/Triassic boundary sections from the Bükk Mts, which include strata with high concentrations of magnetospherules. Since the Paleozoic-Mesozoic rocks of the Bükk Mts are anchimetamorphosed and intensively tectonized, it was decided to carry out a pilot paleomagnetic study on samples from two sections with different dips, before collecting a large number of samples for the intended magnetostratigraphy survey. The results of this study can be summarized as follows. The rocks of the sections possess remanences of pre-tilting age, and the magnetic fabric does not show any evidence of strong deformation. Nonetheless, the magnetization can not be primary since the measured inclinations are far too steep for the Permian/Triassic boundary. The estimated age of the acquisition of the paleomagnetic signal is Late Cretaceous. Although the results are negative in terms of magnetostratigraphy, they deserve attention from a tectonic point of view. The observations suggest that either the studied localities or the entire range of the Bükk Mts was involved in a post-Cretaceous (but pre-Miocene) counterclockwise rotation of about 40°
