The Geological Map of Greenland at scale 1:2.500.000 provides a comprehensive regional synthesis of the geological evolution of Greenland from the earliest Archaean to the Quaternary. The map presents an integrated overview of Greenland’s geological framework, including Precambrian crystalline basement provinces, major orogenic belts, Phanerozoic sedimentary basins and widespread volcanic provinces. Greenland is characterised by large exposures of continental crust dominated by Archaean and early Proterozoic shield rocks that stabilised as part of the Laurentian shield. Younger geological elements are mainly developed along the margins of the shield, where sedimentation, deformation and magmatic activity reflect successive tectonic regimes through time. The map illustrates the distribution and relationships of these geological units and highlights the structural and stratigraphic architecture of Greenland and adjacent offshore areas. The map integrates onshore and offshore geological information and serves as a regional reference for geological interpretation, research, education and resource-related studies in Greenland.

This dataset represents the structure and topography of the Top Chalk surface, i.e. the top of the Chalk Group (including Upper Cretaceous to Danian), in the Danish subsurface. The map illustrates regional variations in the depth and structural configuration of the chalk surface from the central North Sea to the eastern Danish areas. It is based on an integrated geological and geophysical interpretation of seismic profiles, well data and earlier mapping. The map provides an essential basis for geological, geophysical and subsurface reservoir analyses.

The dataset comprises a systematic inventory of onshore petroleum seeps and stains in Greenland. The inventory includes information on approximately 130 localities distributed across Palaeozoic, Mesozoic and Cenozoic sedimentary basins in Greenland. For each locality, coordinates, site descriptions, classification of seep type, geological context, sample numbers and references to reports and publications are recorded. The classification includes oil seeps, gas seeps, mud diapirs and gas-rich springs, oil stains in volcanics, carbonates and sandstones, solid macroscopic bitumen, and fluid inclusions and other evidence of micro-seepage. The dataset synthesises existing knowledge of petroleum systems in Greenland and provides a comprehensive overview of documented natural hydrocarbon occurrences onshore.

Kartet viser utbredelsen av steinkobbe. Latin name: Phoca vitulina. Family: Phocidae. Distribution: Sub Arctic waters along the east and west coasts of both the North Atlantic and north Pacific. In Norway they occur in colonies along the Norwegian mainland coast and on Prins Karls Forland in Svalbard. The harbour seals occur mainly in nearshore areas that are protected against wave action.

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.

This dataset represents a nationwide digital geological map of superficial deposits in Denmark at a scale of 1:200.000. The map shows the classification and distribution of near-surface deposits, primarily glacial and post-glacial sediments. The dataset is based on the Digital Soil and Sediment Map of Denmark at 1:25.000 in areas where detailed mapping is available. In other areas, the distribution of deposits has been interpreted based on borehole data, landscape analysis and other available geological information. The deposits are classified into 12 generalised types, making the dataset a simplified and generalised version of the detailed 1:25.000 map. The dataset provides a national overview of superficial deposits and serves as a reference for regional and national applications.
