Geological map of Denmark, 1:400 000. The Danish Basin. "Base Chalk" and the Chalk Group

The geological maps of Denmark on a scale of 1:400,000 focus on the Danish basin and its geological structures. The map includes areas that extend from the geological age 'Basis Kalk' and the Kalk Gruppen.

The 'Basis Kalk' map shows the depth in metres, where 'Basis Kalk' denotes the area that forms the basis for all layers younger than the Early Cretaceous. Over the majority of the mapped area, this surface is level with the base of the Kalk Group, but where the limestone is eroded away, the surface is equal to the base of the Quaternary. The depth to 'Basis Kalk' is calculated as the depth to the base of the deposits younger than Denmark plus the thickness of the Kalk group.

The map is published in DGU Map Series no. 29 from 1991, where further information about the mapping can be obtained.

Presentation form: Digital map

Purpose: Temaet for de regionale kort er kalkaflejringer fra Øvre Kridt og Danien, her benævnt som Kalk Gruppen. Kortene er udarbejdet om led i en samlet kortlægning af det meste af Jylland med tilgrænsende havområder, og omfatter mod syd dele af Ringkøbing-Fyn Ryggens nordflanke, centralt dele af Det danske Bassin (den danske del af Det norsk-danske Bassin) og mod nord dele af Sorgenfrei-Tornquist Zonen samt af Skagerrak Kattegat Platformen.

Statement: The map is the result of a combined geological and geophysical interpretation of all data collected before 1990. In addition to information from the deep boreholes in the area, it is an interpretation of 20,000 km of reflection-seismic recordings.
