Research output: Book/ReportReport (publicly available)peer-review


Within the framework of the Global Mineral Resource Assessment Project, Greenlandic tungsten resources were estimated down to a depth of 1 km. Two tungsten deposit types, and respective grade/tonnage models, were considered. Eight permissive tracts were assessed for both vein-type deposits and skarn-type deposits. The statistical mean estimate number of undiscovered vein-type deposits is of 11, with 8 expected undiscovered skarn-type deposits. At a 50% probability, these are estimated to contain at least 123.000 and 121.000 tons of W, respectively. The best potential for both vein-type and skarn-type deposits is located in East Greenland, and is related to Caledonian and Devonian granitic intrusions emplaced into metasedimentary rocks of the Krummedal Sucession (Meosproterozoic) and of Eleonore Bay Supergroup (Neoproterozoic). Within this area, the best potential lies mainly within a large tract that extends from northern Scoresby Land to Hochstetter Land, and which includes the Ymers Ø, Knivbjergdal and Alpefjord occurrences, and, accessorily, in another tract, which includes northeastern Milne Land and southern Scoresby Land, as well as Liverpool Land, where the Kalkdal occurrence is located. Furthermore, a tract in South Greenland was considered to hold some potential for vein-type deposits.
