It is regarded as part of an originally continuous orogenic belt (Figure 1) which included the Torngat Orogen of Labrador (KorstgƄrd et al. 1987) and the thrust belts of Northern Norway and the Kola peninsula (Marker, 1988). All the segments are dominated by thrust tectonics and pressures up to 12 kb. In North Norway and West Greenland, juvenile Proterozoic sialic crust formed in association with sutures within the mobile belt. In East Greenland, Juvenile Proterozoic magmas are represented by basic intrusions emplaced into Archean continental crust. The location of the East Greenland section of the mobile belt is thought to have been controlled by pre-existing Late Archean and very early Proterozoic structures.}, number={4}, journal={Geoscience Canada}, author={Bridgwater, D. and Austrheim, H. and Hansen, B.
