Abstract:We review the paleomagnetic studies published on the Northern Calcareous Alps (NCA) and also include data from two theses that were not published yet. Moreover, we present new data from upper Santonian to Maastrichtian Gosau deposits from the Neue Welt Area in the easternmost part of the NCA (D = 325.8. I = 37.1, α95 = 8.3, positive fold test, thus indicating counterclockwise rotation and inclination flattening). Although several of the recently published studies provide valuable data, presently the paleomagnetic data base of the NCA does not provide a sufficient frame work for a quantitatively backed paleogeographic model. By thus documenting the state of research, we want to outline major problems regarding the paleomagnetic characterization of the NCA and also specify the kind of paleomagnetic future work that is particularly needed within this mountain range.
