Continued 1:500 000 reconnaissance mapping in the Precambrian of the Sukkertoppen region, southern West Greenland

Abstract

The reconnaissance mapping programme for the 1:500000 map sheet Frederikshåb Isblink - Søndre Strømfjord (62°30'-66°45'N), in the Godthåb-Sukkertoppen region that started in 1976 (Allaart et al., 1977), was continued in 1977. This summer's activity was concentrated in the areas between the inner part of Fiskefjord and Taserssuaq, from Taserssuaq to north of Majorqaq and from Søndre Isortoq to Evighedsfjord (fig. 19). Between Fiskefjord and Søndre Isortoq detailed mapping has been carried out by geologists of Kryolitselskabet Øresund A/S during the summers of 1965-1976. The coastal areas have been investigated previously by GGU geologists (Berthelsen, 1960; Noe-Nygaard & Ramberg, 1961). The mapping team of five geologists, supported by two Bell G3 helicopters and by the GGU motor cutter F. Johnstrup, operated from a base camp at the head of the fjord Kangerdluarssuk, 30 km north-east of Sukkertoppen. The reconnaissance mapping programme will be completed in 1978, when the area north of Evighedsfjord as far as latitude 66°45'N will be mapped.
