摘要：Te Chalk Group is ubiquitous in the subsurface of the Danish Basin and its upper levels are exposed locally onshore,most notably in eastern Denmark. Although many subsurface studies have been made of the group in the Danish Basin, most of these have been in the eastern part of Denmark(e.g. Esmerode et al. 2007; Surlyk & Lykke-Andersen 2007)whereas the stratigraphy and character of the Chalk Groupin the western onshore region is less well-known. Te workdescribed here was undertaken as a BSc project at the Department of Geosciences and Natural Resource Mangementat the University of Copenhagen by the frst author as part ofregional seismic mapping work contributing to an evaluationof the geothermal energy potential in Denmark. Te aim ofthis paper is to present a summary of the key results of thestudy. We have subdivided and mapped the distribution ofthe Chalk Group in the northern North German Basin andthe south-western Danish Basin based on digital reﬂection seismic profles. We also highlight seismic architectural features that testify to periods of active bottom currents.
