Summary of mineral occurrences and mineral exploration potential of South Greenland (Sheet 1 Geological map of Greenland) [1st version]

The South Greenland map sheet is mainly underlain by gneisses and supracrustal rocks of Archaean age as well as granitoid intrusives and supracrustals of Proterozoic age. Cryolite, graphite and copper have been mined commercially.

Assessment of known mineral occurrences and geological settings suggests that the greatest current potential for the discovery of economically viable mineral deposits is related to gold and diamonds.

Diamond-bearing kimberlite dykes have been investigated within the Archaean craton in the northwest corner of the map area. Evaluation of the known exploration efforts in this area leads to the belief that re-evaluation is warranted.

Vein-type gold mineralization, spatially associated with abundant sulphides and regional deformation, represents an attractive exploration target within this map area. Regional stream-sediment surveys have generated element anomalies in a number of areas that may indicate the presence of previously unknown occurrences of this or other types of mineralization.
