Abstract
The summer of 1973, the second of a six-year series of field studies by teams from the University of Exeter, saw the completion of 1:20 000 mapping of the coast region from Ameralik (Narssaq-Præstefjord) south to Sermilik, i.e. approximately between latitudes 64°N to 63°30'N. The area mapped in detail, which excludes the Qilángârssuit island complex, extends inland for about 10 km. A.D.G. mapped the ground between Ameralik and Buksefjorden, M.R.S. mapped from south of Buksefjorden to, and including, the Tre Brødre anorthosite complex, B.C. covered most of the ground between Tre Brødre and Amitsuarssugssuaq, including Sanerata tima, and P.R.A.W. began work in the area between Alangordlia and Sermilik. B.C. also spent a week at the end of the season making a reconnaissance of Qilángârssuit.

The summer of 1973, the second of a six-year series of field studies by teams from the Vniversity of Exeter, saw the completion of 1:20 000 mapping of the coast region from Ameralik (Narssaq-Præstefjord) south to Sermilik, i.e. approximately between latitudes 64°N to 63°30'N
Previous work in the region has aIready been outlined by Chadwick & Coe (1973) and we wish to repeat that the terminology set up by McGregor (1973) in the Godthåbsfjord region has been applied with somereservation, with regard to the Nftk gneiss, which we can show to have been derived by injection and by remobilisation of older gneisses
The augen gneiss is by definition Amltsoq beeause it is cut by Ameralik dykes but it is clearly younger than its banded host
Summary
The summer of 1973, the second of a six-year series of field studies by teams from the Vniversity of Exeter, saw the completion of 1:20 000 mapping of the coast region from Ameralik (Narssaq-Præstefjord) south to Sermilik, i.e. approximately between latitudes 64°N to 63°30'N. In addition to those known already around Narssaq and on Qilangarssuit, large areas of Amitsoq gneisses, identified by the presence of Ameralik dykes variably preserved as discordant amphibolite sheets or small pods and strips, have been found north-west of Amitsuarssugssuaq, at the entrance to Alangordlia, on the north coast of Sermilik and north of Ikerasagssuaq.
