The map is based on selected seismic data up to 2001. The map shows the structural conditions at depth for the 'Top Kalk' surface, from the central to the eastern part of the Danish North Sea. 'Top Kalk' denotes the surface which forms the basis of the Tertiary deposits (except Denmark). The map is described in GEUS Bulletin No. 13. 2007.

GEUS' Earthquake Portal provides information on all recorded earthquakes in Greenland. The data are extracted from GEUS' earthquake database and are updated daily. As a result, the timing, locations, and magnitudes of events may change as new data are added and existing events are revised. Continuous quality control is carried out, aiming to identify and remove explosions – typically related to military exercises or the removal of old munitions. Therefore, the list may change over time, and some uncertainty may be associated with the determination of epicentres and depths. The portal displays information for each earthquake, including the time of occurrence (year, month, day, hour, minute, second) in Greenwich Mean Time (GMT), the geographical location and depth of the epicentre, and the local magnitude measured on the Richter scale. Earthquake data can be exported from the portal according to the defined zoom level and map extent.

All active small scale licences. The data are converted from the WFS that th ministery of mineral resources (MMR) in Greenland provides. Links are provided in the online resources

The Raw stream sediment samples dataset is data as they have been delivered from the laboratories, i.e. values below detection limit often spelled as negative but zero may also apply. The data are not controlled by a geologist. In addition, they may not have been reported.

Intrusions and magmatic complexes are central, when it comes to an assessment of the economic geological potential of a region. There are many of these in Greenland, and only a few of them have been examined in detail for their economic potential. In Nielsen (2002), tertiary intrusions and complexes in East Greenland were described, and later on information on intrusions and magmatic complexes in all of Greenland, were modelled based on the same methodology. The information has been compiled by GEUS geologists.

Each map displays a grid image of the variation in element concentration, a colour scale giving class intervals for the grid colours, histograms showing the frequency distributions of sample values and grid cell values, respectively, and statistical parameters for measured concentrations in samples and for the grid cell values. All element concentrations below the lower limit of detection for the analytical method have been set to zero for simplicity, and in accordance with their registration in the GEUS database. Major element oxide concentrations have been recalculated as volatile-free concentrations to compensate for the effect of variable contents of organic matter and carbonate.

Dataset containing standard polygons for regions of Greenland and specific hand-drawn polygons representing the areas where the study was conducted that is described in the publication. Data can be filtered for publication title, authors, year of publication and the list of attributes contains other reference information including a link to the publication. The publications include GEUS Bulletin (2020 - ), Geological Survey of Denmark and Greenland Bulletin (2004 - 2019), Geology of Greenland Survey Bulletin (1997 - 2002), Bulletin Grønlands Geologiske Undersøgelse (1948 – 1996) , Danmarks og Grønlands Geologiske Undersøgelse Rapport, Rapport Grønlands Geologiske Undersøgelse (1964 – 1996), Open File Series Grønlands Geologiske Undersøgelse, Mima rapport, Grønlands Geologiske Undersøgelse Geological Map Descriptions and Geological Survey of Denmark and Greenland Map Series.

Only data released to the public will be available to external users over the internet.

The Geological Survey of Greenland (now part of the Geological Survey of Denmark and Greenland: GEUS) carried out a systematic 1 : 500 000 geological mapping program in North Greenland with fieldwork between 1978 and 1985 (Henriksen & Higgins 1991). One of many activities was a systematic programme of oblique aerial photography of the steep walls of fjords and valleys. This web-site makes available more than 6400 of these photographs. Using a map interface the user gain access to the individual images, their geological coding and the geological map).

The dataset contains outlines of geological maps of Greenland printed and published by GGU and GEUS since 1957 at various scales. The dataset contains links to the GEUS Dataverse where each map has been assigned a DOI and can be downloaded in a resolution of 400dpi TIFF-images or pdf.
