Jurassic to Lower Cretaceous pelagic sediments are well known to form a major element of the northernmost tectonic units of the Gresten Klippenbelt (Lower Austria). According to the correlation of the fossil and magnetostratigraphic data, the entire succession of the Nutzhof section embraces a duration of approx. 8 million years (approx. 150-142 Ma). The J/K boundary (the Berriasian Stage base), located near Calpionella Zone base roughly corresponds to magnetozone M19N a succession of M-zones correlative with M17N to M22R. The above reported results strongly suggest that the section mirrors a change of the depositional position of the Nutzhof section from a shallower into a deeper region, and a more stable environment on the European Helvetic shelf to slope during the Late Jurassic to Early Cretaceous time.
