Field work on Precambrian anorthosite and contact rocks, Smithson Bjerge, Inglefield Bredning, North-West Greenland

Abstract

This report gives an account of geological investigations and 1:25000 scale mapping of Precambrian rocks of Smithson Bjerge, at the head of Inglefield Bredning, about 150 km north-east of Thule Air Base. Previous work on this area was restricted to a few days of reconnaissance work in 1971 and several helicopter landings in 1975 (Dawes, 1972, and personal communication, 1978). Table 1 gives the principle geological eveJ;lts of the area and results of the mapping are given in outline in fig. 8.
