Review of the work on The Precambrian Basement (Pre-Gardar) between Kobberminebugt and Frederiksdal, South Greenland

Abstract

The systematic geological mapping in South Greenland under the auspices of Grønlands Geologiske Undersøgelse started in 1956. The Ivigtut region was mapped in the first three years. From 1958 to 1960 a new group mapped part of the so-called Julianehåb granite in an area between Kobberminebugt and Igaliko fjord, to the south-east of the Ivigtut area. In 1961 the work was continued in the area south of Igaliko fjord as far as Frederiksdal and completed in 1963. In the Ivigtut region, as well as in the Julianehåb area, after the large groups left a few geologists continued work for one or two summers to study special problems. In this paper no results from the Ivigtut region will be described, only the different possible interpretations will be mentioned to give a comprehensible background for the treatment of the areas to the south-east.
