Abstract (in english)
   The rockmagnetic studies support the high resolution magnetostratigraphic research of the J/K boundary at Nutzhof. This profile is compound of limestone-, marly limestone- and marl succession. The outcrop is part of the Pieniny Klippenbelt of Lower Austria, which is surrounded by the Rhenodanubian Flysch Zone. Isothermal remanent magnetization (IRM) to saturation was measured to identify coercivity spectra. Magnetite can be found in all limestone layers on the Nutzhof J/K boundary. Due to its extremely high magnetic susceptibility (MS) and natural remanent magnetisation (NRM) is the most important magnetic mineral on the profile. Its' Curie point is at 470°C, which means that there is high titanium content in the magnetite lattice. The most probable explanation is that the magnetite has detrital origin and it contain primary NRM komponent.
