Geological Map of Denmark, 1:400.000 - The Danish Basin: Base Chalk and the Chalk Group

The dataset comprises a geological map of the Danish Basin at a scale of 1:400,000 presenting regional thematic maps of the Base Chalk and the Chalk Group. The map was published in 1993 as part of the DGU Map Series no. 29 and was produced as part of regional geological mapping of the basin. The mapping is based on interpretation of seismic data supplemented by information from deep onshore and offshore boreholes. The dataset consists of several thematic sub-maps that together show the depth to the Base Chalk and the vertical thickness (isochore) of the Chalk Group. The map covers the Danish Basin and adjacent areas and was produced to support regional structural and stratigraphic interpretation.

Beskrivelse: The map was published as DGU Map Series no. 29 in 1993 and was produced based on regional interpretation of seismic data supplemented by information from deep onshore and offshore boreholes. The data basis includes both publicly available and proprietary seismic data acquired over several decades prior to publication. The seismic and borehole-based interpretations were used to compile regional maps of the depth to the Base Chalk as well as thickness maps of the Chalk Group. The dataset represents the geological interpretation available at the time of publication.
