This dataset comprises calibrated geochemical data from stream sediment and soil samples collected in North Greenland between 1978 and 1999, supplemented by extensive reanalyses in 2011. The dataset includes selected elements relevant for the evaluation of zinc mineralisation: CaO, K₂O, Ba, Cu, Sr and Zn. A total of 2,469 stream sediment samples and 204 soil samples were included. The analytical values represent the most reliable results following systematic quality control and calibration procedures designed to eliminate bias between analytical methods and analytical periods, as described in Thrane et al. (2011). All values below detection limit are coded as 0 in the dataset. The dataset supports regional assessment of geochemical patterns and mineral potential in North Greenland.

This dataset comprises regional geochemical stream sediment data from West and South Greenland and forms the basis of the Geochemical Atlas of West and South Greenland (Steenfelt, 2001). The Geochemical Atlas of West and South Greenland presents the results of a regional stream sediment geochemical mapping programme conducted between 1979 and 1998. A total of 7,122 stream sediment samples were collected from low-order streams with near-uniform spatial coverage across West and South Greenland. The <0.1 mm grain-size fraction of 500 g samples was analysed for major and trace elements using X-ray fluorescence spectrometry (XRF), instrumental neutron activation analysis (INAA), delayed neutron counting (DNC) and loss on ignition (LOI). After systematic calibration and quality control to eliminate analytical bias between different methods and time periods, a harmonised and internally consistent dataset was established containing up to 43 elements per sample. The atlas provides a regional overview of the geochemical composition of the minerogenic fraction of stream sediments and constitutes a geochemical baseline dataset for geological mapping and mineral exploration in Greenland.

Sirkumpolært grunnkart med transparent hav som kombinerer topografiske detaljer fra Kartverket og Norsk Polarinstitutt syd til X breddegrad (sør-Frankrike). Det inneholder også kartdata fra de andre arktiske landene som er tilgjengeliggjort gjennom Arctic Spatial Data Infrastructure (Arctic SDI). Kartet inneholder ikke sted- og veinavn, disse kan legges på gjennom tjenesten sirkumpolære stedsnavn cache.

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.

The dataset comprises regional airborne radiometric measurements acquired in Greenland during 1975–1982 as part of systematic geophysical mapping programmes. The measurements were collected using aircraft-mounted gamma spectrometers and record natural gamma radiation from potassium (K), thorium (Th) and uranium (U). The surveys covered large parts of Greenland and were conducted to support regional geological mapping and mineral exploration. The data constitute a historical geophysical reference dataset for analyses of near-surface lithological variations and the distribution of radioactive elements.

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.

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 dataset contains recorded earthquakes and seismic events in Greenland. The data include information on event time, geographic location (epicentre), depth and magnitude for confirmed and suspected earthquakes. The dataset is based on observations from GEUS’ seismic monitoring network and is used for monitoring, research and dissemination of seismic activity in Greenland.
