Geological map of Denmark, 1:200,000 - The Danish Central Graben: Top Chalk and Post-Chalk Group

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of ‘Top Chalk’ and the Post-Chalk Group in terms of two-way travel time, depth and interval velocity. The map was published in 1995 as part of the DGU Map Series no. 47 and was produced as part of a comprehensive geological mapping of the Danish Central Graben.

The mapping is based on interpretation of seismic data supplemented by information from boreholes. The map covers the Danish part of the Central Graben and parts of the eastern North Sea block, and adjacent areas in the Norwegian, British and German sectors are included where data were available in order to define regional structural relationships. The map sheet comprises several thematic sub-maps that together describe regional variations in structure and stratigraphy.

Purpose
The purpose of the dataset is to document the regional geometry, depth variation and velocity characteristics of ‘Top Chalk’ and the Post-Chalk Group in the Danish Central Graben, thereby providing a basis for regional-scale stratigraphic and structural interpretation. The dataset is intended for use in geological and geophysical analyses as well as basin and resource studies.

Supplemental Information
The dataset is a map product at a scale of 1:200,000 and should be used with consideration of the map scale and level of generalisation. The map is part of the DGU map series and is based on the data coverage and interpretation available at the time of publication. The map sheet consists of several sub-maps that together form the complete presentation.

Statement
The map was published as DGU Map Series no. 47 in 1995 and was produced based on regional interpretation of seismic data supplemented by information from boreholes. The mapping work was initiated in the mid-1980s and completed towards the time of publication. The seismic interpretations were used to compile regional maps of two-way travel time and depth to ‘Top Chalk’ as well as an interval velocity map of the Post-Chalk Group. The dataset represents the geological and geophysical interpretation available at the time of publication.
