Nationwide geophysical database for environmental and raw material data, also known as GERDA (GEophysical Relational DAtabase). The database contains various types of geophysics, including geoelectrics, electromagnetics, borehole logs and seismic. All data is freely available for download on the GEUS website. The database is updated continuously.

The Greenland Geochronology Database is a systematic compilation of published U-Pb geochronological data from Greenland. The dataset integrates age determinations from a wide range of scientific publications and normalises isotopic ratios and uncertainties into a consistent format, with all analytical errors reported at the 1 sigma level. Ratios have been verified against reported ages and corrected where necessary to ensure internal consistency. The database is structured to enable efficient querying and cross-comparison of geochronological information derived using different analytical standards.

The dataset contains polygons representing applications for mineral-related activities in Greenland, including exploration and exploitation licences. The dataset includes different processing statuses such as Approval Applications, Licence Pending and Under Review. The data are based on geographic information provided via WFS by the Ministry of Mineral Resources in Greenland and are redistributed without modification of the original boundaries. The dataset provides an overview of areas where licence applications are under review or awaiting decision.

The dataset contains polygons representing selected protected and regulated areas in Greenland relevant to mineral activities. The areas include UNESCO World Heritage Sites, nature protection areas, and zones with specific restrictions or prohibitions on mineral activities. The dataset is converted from a WFS service provided by the Ministry of Mineral Resources in Greenland and is used as a geographic reference in the assessment of exploration and exploitation licences. The polygons represent administrative boundaries and do not constitute a legally binding representation of current legislation.

The dataset comprises geochemical analyses of 1,269 soil samples collected in Greenland from 1974 onwards as part of systematic geochemical mapping and mineral exploration programmes. Soil samples were primarily collected in areas lacking developed stream channels where stream sediment sampling was not feasible. The samples represent surface material and have been analysed for major and trace elements using various laboratory methods including X-ray Fluorescence Spectrometry (XRF), Instrumental Neutron Activation Analysis (INA), Inductively Coupled Plasma Emission Spectrometry (ICP), and Atomic Absorption Spectrometry (AAS). The dataset contains the original analytical results as received from the laboratories together with administrative information on sample location and analysed grain-size fraction. The data form part of the analytical basis for the Geochemical Atlas of West and South Greenland.

The dataset contains geochemical analyses of 49 scree (talus) samples collected in Greenland as part of regional geochemical mapping programmes conducted by the Geological Survey of Greenland (GGU), later GEUS, between 1977 and 1997. Scree samples were collected in areas where neither stream sediment nor soil sampling was feasible. The samples represent near-surface material derived from local bedrock and were analysed for major and trace elements using laboratory methods available at the time of collection. The dataset supplements regional geochemical data from stream sediment and soil samples and forms part of the overall basis for geochemical mapping in Greenland.

The dataset contains aeromagnetic measurements acquired during 1993–1996 in East and North-East Greenland as part of the AWI-AEROMAG project conducted by the Alfred Wegener Institute (AWI). The measurements represent regional airborne magnetometry and include total magnetic field intensity corrected for diurnal variations and the main geomagnetic field. The survey was carried out to support geological mapping and tectonic analysis of eastern Greenland. The dataset constitutes an important geophysical reference for studies of crystalline basement rocks, sedimentary basins and structural features in the region.

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of ‘Base Chalk’ and the Chalk Group in terms of two-way travel time, depth, interval velocity and vertical thickness (isochore). The map was published in 1995 as part of the DGU Map Series no. 48 and was produced as part of a comprehensive geological mapping of the Danish Central Graben. The mapping is based on regional 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, and adjacent areas in the Norwegian, British and German sectors are included in order to define regional structural relationships. The map sheet consists of several thematic sub-maps that together describe the structure and stratigraphy of the area.
