Field work on Precambrian granites and metasediments in the Søndre Upernavik – Kuvdlorssuaq region (72°00'–74°40'N), northern West Greenland

Abstract

The 1979 field work was the last of a series of three GGU reconnaissance mapping expeditions in the Søndre Upernavik - Kuvdlorssuaq region. The investigations aimed at the production of the 1:500 000 geological map sheet of the Marmorilik - Melville Bugt region. However, at the end of the 1979 field season it became clear that enough field data had been collected for the production of a series of six 1: 100 000 geological map sheets covering the region between 72 0 00' and 75°00'N. Support was again provided by the GGU motor cutter K. J. V. Steenstrup with Andreas Vidstein as skipper. To consolidate the work of previous field seasons, time was spent in correlative work and re-investigation of certain areas. Special attention was given to the Prøven charnockite complex and the stratigraphy of the metasedimentary cover. A preliminary general outline of the regional geology was given by Escher & Stecher (1978).
