Precambrian crustal evolution and Cretaceous–Palaeogene faulting in West Greenland: Presentation and interpretation of structural data from the Nagssugtoqidian orogen using a GIS platform: general trends and features
In this contribution we present data collected by more than 50 international geologists involved ingeological mapping and research projects in the Nagssugtoqidian orogen of West Greenland, organised by the Geological Survey of Denmark and Greenland and the Danish Lithosphere Centre.
