Abstract
Several occurrences of pitchblende have been discovered in widely spaced locations in the wider surroundings of Narssaq, Narssarssuaq and Julianehåb in South Greenland. The mineralisation occurs in veins within the Proterozoic granite. The paragenesis and age (1180 m. y.) suggest that this mineralisation is derived from hydrothermal activity associated with the emplacement of the Gardar alkaline complexes and their parent magmas.
The veins are controlled by fracturing and faults cutting the granite, which formed in response to the Gardar magmatic and structural events 1330–1150 m. y. ago.
