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. Magnetite has detrital origin and it contain primary NRM component.
