Abstract
A numerical model that was developed for the simulation of the genesis of Maastrichtian wavy-bedded (Tuffaceous) Chalk precession cycles of Maastricht (SE Netherlands) and the Gironde Estuary (SW France), is used to explain the sedimentology of the wavy-bedded Maastrichtian-Danian (Tuffaceous) Chalk sequence of Stevns Klint (Denmark). It appears that the Stevns Klint K/T boundary Fish Clay with an abnormally high iridium concentration reflects the dissolution of carbonate and the concentration of insoluble authigenic minerals (condensation) during a period of exceptionally low deposition rates, that presumably coincided with a rather low-energetic precession period, during a sudden change of tectonic regime.
