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The dataset contains outlines of archived historical unpublished geological maps and sections of Greenland mostly created by GGU and GEUS but also some other institutes from 1916 onwards at various scales.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

Samples of surface material, i.e. stream sediment, soil, and scree have been collected over large parts of Greenland from 1974 onwards mainly as part of mineral exploration programmes and more broadly for geochemical mapping by means of stream sediment (Steenfelt 1999, 2001). Following various sample preparation procedures, like drying and screening, making concentrates of heavy minerals from stream sediment or soil, certain fractions of the samples have been chemically analysed at diverse laboratories where a range of analytical methods were applied as they became available over the years. The present dataset contains the analytical data from stream sediment as they were received from the laboratories together with administrative data, including sample location and grain-size fraction analysed. Many samples have been analysed at more than one laboratory and by more than one method and the analytical data for each sample and grain size fraction are listed lab by lab and method by method in the same row. The majority of the samples were collected and analysed before year 2000. More recent data from South-East and North Greenland have been added (Kolb et al 2016).

The place names data set is from the book 'Northern East Greenland's research history and place names' by A.K. Higgins, which GEUS published in 2010, with associated maps which have now been converted to web GIS format. Via free text search, you can find the place names with their explanations and their location on the map.
