Glaciotectonic deformation has a large impact on the stratigraphical andlithological variability of Quaternary deposits and the shallow subsurfacepre-Quaternary sediments. Mapping of the distribution of glaciotectonicdeformation involving pre-Quaternary and interglacial deposits has beencarried out, and the density of glaciotectonic deformation analysed, on thebasis of data from the well database ZEUS, at the Geological Survey ofDenmark.Glaciotectonic deformation is widespread in Denmark. It is recognisedin glacial terrains within morphological well-defined glaciotectonic complexes, and in areas with no obvious glaciotectonic related morphology aswell as in areas covered with postglacial deposits. The dislocated bedrockis usually not transported for long distances, although rafts of pre-Quaternary bedrock may be transported up to 50 km or more.On a large scale, regions have been located showing high intensity ofglaciotectonic deformation. Some of these regions are in good agreementwith records from exposures and the geomorphology, others cannot be recognised without well log information.
