Till variation in a Weichselian glacial section along the coast of southwest Funen, Denmark

Abstract

In a 5 km long coastal cliff section in SW Funen till variation in Weichselian glacial sequences has been studied. In the central part of the exposure the presence of two till units separated by stratified sands and gravels is immediately apparent. Within each of these two units several lateral facies could be distinguished. The lower till unit is a basal till consisting of a massive and a brecciated facies. In the genetically complex upper till unit four different facies are present: two flow till facies, a supraglacial lacustrine facies and a transitional facies. The fourth type has been classified as transitional since it presumably represents a flow till which after its supraglacial deposition has been partly transformed into a subglacial till during a later glacierization phase. This interpretation is based on both the general glacial history of the cliff and specific characteristics of this facies type, primarily its gradual lateral change in sedimentary structure
