Various field relations of the basic dyke swarms near Sukkertoppen have been described (Ramberg, 1948; Berthelsen & Bridgwater, 1960; Windley, 1970) and a preliminary chronology suggested (Bridgwater et al., 1976). The Kangâmiut dykes are noteable in that the central portion of some of the dykes has been converted into amphibolite and garnet amphibolite (Ramberg, 1948; Windley, 1970). Otherwise they appear as normal dolerites.
