The Danian chalk and limestone help to form Stevns Klint, and the Sangstrup, Karlby and Bredstrup cliffs.

The deposits consist of conglomerates, sands, marls, and clays. Overlying the Paleocene deposits are the Eocene clays. These lie against the lower border of the glacial deposits in a much broken belt which can be traced from southern
