The distribution of potentially diamondiferous rocks in West Greenland shows a concentration within the area from 60°N to 69°N. Outside this area occurrences are scarce. In total nearly one thousand localities with kimberlitic rocks in West Greenland have been recorded, of which nearly 2/3 are found within a major alkaline province in the region around 66°N. The density 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 from 1992–2003 has mainly focused on the major alkaline province. The investigations of the remaining part of southern West Greenland has been of more regional character.
