Resumé
Graphitic schists commonly occur in the Proterozoic supracrustal series, incorporated in Archaean basement, in Proterozoic greywackes in central West Greenland and in rocks of the Ketilidian mobile helt of Proterozoic age in South Greenland.
A special type of graphite occurrence is found in Cretaceous coal-bearing sediments on the Nuussuaq peninsula that have been contact metamorphosed by intrusive peridotitic dykes.
This review draws on a number of reports from the beginning of this century at the culmination of the search for economically viable graphitic deposits. Only those graphite occurrences that have been assayed or more throughly explored are reviewed_. One deposit, on Amitsoq island in South Greenland was exploited from 1914 to 1922. One deposit, named Akuliaruseq has been explored in greater detail in recent years. The geographical position of the reviewed graphite occurrences in Greenland is indicated on the index map.
Modern Greenlandic orthography of place names has generally been used in this review.
