Contrasting views on the Weichselian glaciation and deglaciation of Denmark

Recent kineto-stratigraphic studies (Berthelsen, Bull. Geol. Soc. Denm. 27 , 1978) indicate repeated advances and recessions and a correspondingly complex pattern of deglaciation. From mainly morphological studies Marcussen ( Danm. Geol. Unders . II: 110. 1977) advocates that only one Weichselian advance (from N and NE) occurred. Two of his key areas are discussed. His deglaciation model involves the formation of successively lower plains during the late Middle Weichselian due to glaciofluvial and ablation processes. It is shown that this model must be abandoned, because its implications contradict its basic assumptions.
