Geological, geochemical and ecological research in the Ilímaussaq region, South Greenland

Abstract

In 1977 field work was concerned with the lujavrites and kakortokites of the south-eastern part of the Ilimaussaq alkaline intrusion (see Andersen & Bohse, this report), pegmatites and veins within the intrusion, the Narssaq intrusion situated to the west of the Ilimaussaq intrusion, and the environmental geochemistry and the ecology of the Narssaq region. Preliminary results of the field work and of some of the laboratory investigations are reported below. It should also be mentioned that a diamond drilling programme was carried out in the uraniferous rocks of the Kvanefjeld area in the northern part of the Ilimaussaq intrusion (see Nyegaard, this report).
