Investigations on the Nagssugtoqidian boundary between Holsteinsborg and Kangâmiut, central West Greenland

Abstract

The southern boundary of the Nagssugtoqidian mobile belt was first mapped by Noe-Nygaard & Ramberg (1961) on the basis of the progressive deformation of a swarm of basic dykes - the Kangarniut dyke swarm. Field work in 1969 showed this boundary to have an approximate NE-SW strike (Eseher et al., 1970). The object of the summer's field work reported on here was to continue the investigations along the Nagssugtoqidian boundary and to study the deformation- metamorphism-dyking relationships in the western part between Holsteinsborg and Kangamiut. The field work formed part of a joint project involving the University of Liverpool. Transport in the field was supplied by the GGU cutter "A. Kornerup" with Orla Norsk as skipper.
