Abstract
During recent geological mapping of the Nigerdlikasik area, 45 km due east of Frederikshåb, an intrusive diatreme was discovered. This takes the form of a 50 cm wide vertical dyke, tracable for at least 500 metres. It can be demonstrated that the petrographic features of this and several other bodies occurring in the vicinity, e. g. in the Tigssaluk granite (Emeleus, 1958) and on Midternæs, (A. K. Higgins, personal communication), conform to the definition of a kimberlite as outlined by Dawson (1967).
