Central West Greenland exposes a large region of Archaean continental crust that was rifted and subsequently reworked in the Palaeoproterozoic during the Nagssugtoqidian and Rinkian orogenies. The southern margin of the Nagssugtoqidian orogen with its deformed Kangâmiut dykes is a classic example of an orogenic front, the central part of the orogen displays Palaeoproterozoic collisional structures, and the northern part illustrates strain partitioning at regional scale. The region also displays onshore expressions of the Cretaceous–Palaeogene break-up of eastern Laurentia. This bulletin contains ten research papers dealing with the Archaean and Palaeoproterozoic crustal evolution in the southern and especially northern parts of the Nagssugtoqidian orogen, a paper on the cooling history of the Rinkian fold belt farther north, and a paper presenting a detailed remote sensing and field geological analysis of onshore brittle structures in the central Nagssugtoqidian orogen, which are related to the Cretaceous–Palaeogene Ungava fault zone in the Davis Strait.
