Abstract

The intrusion of the Precambrian dykes of the area between Igaliko Fjord and Redekammen probably spans the greater part of the Gardar period. These dykes consist of various generations of lamprophyres, olivine dolerites, feldspar xenocryst dykes, and just saturated and undersaturated microsyenites. Often the alkaline dykes are composite. A tentative chronological interpretation, mainly based on intersections, is presented.
