Paleomagnetism of Permian-Triassic sections, Bükk Mts, Hungary

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 Bukk Mts, which include strata with high concentrations of magnetospherules. Since the Paleozoic-Mesozoic rocks of the Bukk 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...
