The sedimentary sequence of a Weichselian intraglacial lake at Ormehøj (Funen, Denmark)

Abstract

Weichselian deposits have been investigated in a high kamiform hill of the Vissenbjerg dead-ice landscape. The sediments were formed by the gradual infilling of an intraglacial lake underlain by a basal till. Normal deposition by a prograding delta was interrupted by the catastrophic bursting of a supraglacial lake. resulting in a boulder bed. Various facies can be distinguished. though vertical and lateral relationships often are obscured by diapiric activity of a subjacent clay. The meaning of the terms 'supraglacial' and 'intraglacial' (often used in a confusing way) is shortly discussed
