The authors carried out geological mapping in August 1987 at the south-eastern boundary of the Finnefjeld gneiss complex around 65°N. The field work was supported by the GGU cutter 'J. F. Johnstrup'. Based on reconnaissance mapping in the 1950s Berthelsen (1951, 1957,1962) divided the Archaean gneiss terrain in the southem Sukkertoppen district between Godthåbsfjord and Søndre Isortoq into three major tectonic units: the Nordland, the Finnefjeld and the Alangua complexes. This division was also followed by Noe-Nygaard & Ramberg (1961).
