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.

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The dataset contains outlines of archived historical unpublished geological maps and sections of Greenland mostly created by GGU and GEUS but also some other institutes from 1916 onwards at various scales.

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.

Zircon age data as gathered from literature and GEUS samples

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.

Ujarassiorit is a mineral hunt competition open to residents of Greenland. Participants can submit rock samples from Greenland to the Ministry of Minerals Ressources (MMR) for evaluation and may be selected for a prize.

The digital geological map shows the surface geology. The map is a result of the systematic geological mapping of Denmark. The map is digitized from maps originating from fieldwork, where sediment samples are collected at 1m depth using a hand auger with a sample spacing of 100 - 200 m. This version 6 from 2021 classifies 91 % of Denmark's area. The map is supplemented in an ongoing process. The legend shows 82 different sediment types. The map is published in GEUS report 2021/68, where further information is available in Danish.

Scree samples have been collected when both stream sediments and soil samples have proven impossible. The available data package contains 49 samples. Values below detection limit, is given as negative values.

This view presents data from stream sediment geochemical mapping of West and South Greenland (Steenfelt, 2001a). Stream sediment samples were collected from 1979 to 1998 with as even coverage as possible from low-order streams and with a sampling density of mostly around 1 sample per 30 km2 but up to 1 sample per 5 km2 in parts of South Greenland. The 0.1 mm grain size fractions of 500-g samples were analysed for major and trace elements by two or three methods. After careful quality control, selection of the most reliable analytical data and elimination of analytical bias (calibration), the final consistent dataset, named batch 2005, contains data from 7122 samples analysed for up to 43 elements (see Steenfelt 1999, 2001b for details on data selection and calibration). In batch 2005, values below lower detection limit are indicated by the digit 0. Sample location Before 1997, sample sites were originally marked on topographic maps at the scale 1:100,000 and their positions were later digitised and later again corrected, when a new topographic reference was introduced around year 2000. From 1997 onwards, GPS was used to determine sample positions.
