摘要：The scenic coastal cliff of Stevns Klint is a classical study locality that stretches for 15 km along the east coast of Sjællandand it holds arguably the best exposed Cretaceous−Tertiaryboundary in the world (Fig. 1; Damholt & Surlyk 2012). Thefamous boundary separates the soft Cretaceous chalk fromthe harder overlying Tertiary bryozoan limestone (Fig. 2),and the difference between the two rock types controls thecharacter of the frequent cliff falls. The relatively soft chalkat the base is eroded by storm waves and is subject to generaldebris shedding. The overlying bryozoan limestone, withits hardgrounds and flint layers, is more resistant to erosionand is strong enough to form overhanging projections of thecoastal cliff that result in large and small recurring collapses.
