GEUS 3D Geological Model Database

The database is an archive for 3D Geological Models, intended to facilitate their use across various modelling tools, as well as provide a visual and quantitative understanding of the subsurface geology to other professionals, public decision makers and the general public.

A 3D Geological Model is created from various types of geological data, such as borehole logs, seismic surveys, geological maps, and geophysical data. Such a model does not present the reality of the subsurface, but rather shows specialists’ work towards making a coherent and realistic model from the data and modelling tools that are available at the time of modelling.

National Geological 3D Model

The 3D model covers the succession’s development from the oldest, top Pre-Zechstein surface (cirka 258 million year old) up to the Late Cretaceous period, which ended about 61 million years ago. The model layers, the deepest of which lies at approx. 10 km, are based on interpretation of seismic data that have been gridded into 400x400 m cells. The model was prepared by GEUS in 2016, in connection with regional mapping of the geothermal potential to show where the heat from the earth's interior can best be exploited (see also the ‘Deep Geotermi WebGIS portal’).

GeoPower regional Model

The model consist of surfaces and each surface delineates the base of a geological unit. Two adjacent surfaces therefore delineate a geological layer. The deepest and oldest layers in the model are situated at 10 km depth and are more than 258 million years old. The model features detailed geological structures, showing, for instance how old marine salt deposits have moved upwards through overlying younger geological units.


The DK-model is the national hydrological model for Denmark. It has been developed on an ongoing basis by GEUS since 1996 and covers the whole country and outlines both the natural hydrological cycle and the impacts of human activities. The latest official release updated in connection with the Water Management Plan in 2019, is set up in 100x100 m grid cells and contains up to 28 hydrogeological layers covering the distribution of aquifers in the Danish geological strata series. The model covers the upper part of the Chalk Group, Paleogene, Neogene and Quaternary sediments.
