In 1938 E. Wegmann divided the rocks of southern Greenland into and old basement and a younger formation. The basement consists of the remains of a mountain chain for which Wegmann introduced the name the Ketilides. The younger rocks, which are separated from the Ketilidian orogeny by a long period of denudation, were grouped in the Gardar formation. The Gardar "formation" comprises supracrustal rocks, a great number of dykes and a limited number of plutonic bodies. In this article an outline of the geology and the magmatic evolution of the Gardar province will be given.
