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 development of the new magnetic compilation for Greenland (GREENMAG) was initiated in 2021 by the Satellite and Aerogeophysics group at Christian-Albrechts-University (CAU) in Kiel, Germany, in collaboration with GEUS as part of the ESA project GOCE+Greenland. The presented magnetic anomaly map covers all of Greenland, including the Inland Ice and adjacent shelf areas. The map is based on all available modern regional aeromagnetic surveys from Greenland and also includes satellite-based magnetic data where airborne data are not available. The purpose of the compilation is to provide a consistent regional magnetic anomaly map for use in geological interpretation and geoscientific 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.

This dataset provides access to non-confidential mineral exploration licence reports and other geoscientific reports submitted to the Greenlandic authorities in accordance with the Mineral Resources Act of Greenland (effective 1 January 2010) and associated regulations. The reports are subsequently transferred to GEUS for archiving and dissemination. The database allows users to search reports using alphanumeric and geographic criteria, to access report metadata and to download available reports as PDF files. The dataset supports transparency and accessibility of geoscientific information related to mineral exploration activities in Greenland.
