The Kangerlussuaq Alkaline Complex consists of a group of intrusions covering an area of about 900 square kms, located west of Kangerlussuaq on the coast of eastern Greenland. It includes the main Kangerlussuaq intrusion (dating back to about 50 million years ago) and a series of satellite intrusions.
