Structural and sedimentological characteristics of a Weichselian kame terrace at Sønderby Klint, Funen, Denmark

Abstract

At a coastal cliff near Sønderby, SW Funen, the internal structure of a Weichselian kame terrace is well exposed. It exhibits, though in a rather deformed state, a sequence of lodgement till overlain by stratified glaciofluvial beds plus a capping of flow till. An elongated ridge, interpreted as an intraglacial crevasse-infilling, is perched right on top of the kame terrace, whereas laterally the terrace body passes into a small sandur. The kame terrace and the overlying kame ridge are interpreted to be the result of two subsequent oscillations of the Belt glacierization stage. The effect of static load diapirism is demonstrated and the presence of slump structures in a seemingly anomalous spatial attitude is explained. By combining geomorphological, sedimentological and tectonic data, the depositional and deformational history of the kame terrace and associated landforms is reconstructed.
