    The digital terrain model of Greenland is constructed on the basis of GEUS's topographic data set from the official geological maps of Greenland in scale ratios 1:100 000 and 1:500 000. The data base is primarily supported by contour lines, coastlines and support points. The terrain model is assembled as a mosaic in sub-areas based on the map sheet frames from the geological map of Greenland in 1:500 000. The terrain model is made in the coordinate system WGS 1984 Complex UTM Zone 24N with the dimensions in a 100 x 100 m grid. Based on the digital terrain model, a shadow map of the terrain has been constructed.

    Historical mineral exploration and exploitation licences in Greenland. The data are converted from the WFS that the ministery of mineral resources (MMR) in Greenland provides. Links are provided in the online resources.

    The geophysical data available on the Greenland Mineral Resources Portal are both released company data and data acquired based on public funding (AEM and Aeromag surveys). The AEM Greenland 1994-1998 project, encompassed high resolution detailed multi-parameter surveys (electromagnetic, magnetic and partly radiometric) in the years 1994, 1995, 1996, 1997, and 1998 survey 1 and survey 2 producing a total of 75 000 line kilometres. The Aeromag projects, encompassed high resolution magnetic surveys conducted in 1992, 1995, 1996, 1997, 1998, 1999, 2001, 2012 and 2013 producing a total of more than 550 000 line kilometres. The projects were financed by the governments of Greenland and Denmark. More detailed information on the available geophysical date is given in Geology and Ore No. 22.

    The Atlas samples of N Greenland package are described in Thrane et al 2011. This package builds on samples collected over a period from 1978 to 1999, holding old and newly acquired data. Some of the old samples have been reanalysed and together they have been quality controlled and compared. There are 2,644 unique samples in this package (65 of these samples are located under Soil samples). The geochemical analyses that are presented are above detection limit and readings below have been filtered out. Sampling The sampling density is not consistent throughout the covered area, and varies from 1 sample per 30 to 50 km2 to scarce and irregular in other areas. The regional geochemical surveys undertaken in North Greenland, follows the procedure for stream sediment sampling in Steenfelt, 1999. Thrane et al 2011, give more information sampling campaigns in the area. The sample consists of 500 g sediment collected from stream bed and banks into paper bags. In the filed the samples were dried and sent to Copenhagen for further drying and screening. Analyses was made on a split fraction < 0.1 mm size fraction.

    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.

    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.

    In the present database there are 1269 unique samples. Soil samples have been collected in areas without river beds. Preferably stream samples have been collected, but areas where temporarily no stream beds are present, soil samples have been collected as an alternative for geochemical mapping purpose. Five samples in this package are originally from the report Compilation of data sets for a geochemical Atlas (Steenfelt, 1999). These samples have been analysed by "UNKNOWN" methods at "UNKNOWN" laboratories. In fact these samples have been calibrated and corrected for analytical bias, see Steenfelt 1999, for further information.

    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 geologist and will be augmented through more information forthcoming through GEUS and company activities. Only data released to the public will be available to external users over the internet.
