Diamond exploration in Greenland
More than 1000 observations representing in situ kimberlitic dykes are now known in West Greenland, of which 2/3 are found within a major alkaline province in the region from 65°N to 67°N. To date, approximately 900 diamonds have been reported from kimberlitic rocks. The distribution of occurrences appears to partly reflect the uneven degree of investigation of different areas, and partly the fact that the rocks often occur in swarms. The commercial exploration carried out in West Greenland during the period 1992–2004 has mainly focused on the major alkaline province. The investigations of the remaining part of southern West Greenland have been of a more regional character.
