The zinc potential in Greenland

Assessment of undiscovered sediment-hosted zinc deposits

Zinc showings and occurrences are numerous in Greenland. In particular, the Palaeozoic Franklinian Basin, North Greenland, which extends for more than 2,500 km E–W through the Canadian Arctic Islands and northern Greenland, and is dominated by geological settings favourable for sediment-hosted zinc deposits, is considered to carry a large potential for hosting undiscovered zinc deposits. Until now the Palaeoproterzoic sedimentary rocks have been the most important Greenlandic zinc source, namely the Black Angel mine. However, zinc is also known from several occurrences in the Archaean, and the Meso- to Neoproterozoic and Phanerozoic sedimentary environments of West and East Greenland.
