Time-transgressive tunnel valley formation indicated by infill sediment structure, North Sea - the role of glaciohydraulic supercooling

published at : Reconstructing ice-sheet dynamics from subglacial sediments and landforms. Special issue


Structure and lithology of the infill sediments from 16 subglacial buried tunnel valleys of Pleistocene age in the North Sea were analyzed using 3D seismic data and geophysical log data from 5 hydrocarbon exploration wells. The infill sediments are characterized by 3 seismic facies. A model for the formation of these typical sediment successions is proposed in which valley incision and infill are causally linked. This model is based on the theory of glaciohydraulic supercooling beneath ice-sheet margins, and it yields a new insight into possible processes of tunnel valley formation in general
