Reconnaissance for mineral occurrences in North-East Greenland (76°–78°N)

Abstract

Reconnaissance for indications of potentially economic mineralisation in the Caledonian fold belt of North-East Greenland has shown that stream sediment geochemical anomalies and mineral occurrences are related to Lower-Middle Proterozoic and Caledonian skarns, Caledonian shear and thrust zones, and breccias in post-Jurassic normal faults. None of the mineral showings are of economic significance. Mineralised rock samples, stream sediment silt samples and panned stream sediment heavy mineral concentrates generally have low contents of metals and incompatible elements, and only few areas stand out as being geochronically anomalous. On the basis of the present knowledge of the geology of the region the mineral potential is considered low.
