Heavy mineral concentrate geochemistry from Greenland
The dataset contains geochemical analytical results for 725 heavy mineral concentrate samples collected by GEUS in Greenland as part of various geological mapping and mineral exploration activities. The samples originate from several campaigns, including a regional campaign conducted between 1982 and 1986 in the Nuuk area, a 1991 campaign in the southern Nuuk region, and samples collected in 2003 in the Qaanaaq region. Additional samples derive from smaller projects and campaigns with limited documentation. Analyses were carried out at different laboratories, including Activation Laboratories and Bondar-Clegg in Canada and Risø National Laboratory in Denmark. The dataset contains raw analytical results, and metadata concerning sampling procedures and analytical quality are not complete for all samples.

The samples were collected in several independent campaigns and projects carried out by GEUS in Greenland. Between 1982 and 1986 a regional campaign was conducted in the Nuuk area, where gravel and sand samples were collected, sieved, panned and separated using heavy liquids before sub-samples were analysed for a range of elements. In 1991, 106 streams in the southern Nuuk region were sampled and heavy mineral concentrates were produced by wet sieving and rotary panning techniques. In 2003, samples were collected in the Qaanaaq region and concentrates were produced by sieving and heavy liquid separation. Analyses were performed at different laboratories, including Activation Laboratories, Bondar-Clegg and Risø National Laboratory, and analytical methods and detection limits vary between campaigns. For a number of samples documentation of sampling and analytical procedures is limited. Results below detection limits are in some campaigns reported as 0 or as negative values, and elements not analysed may be indicated as 0 or left blank. The dataset represents raw analytical results and is not harmonised across campaigns.
