Field mapping and geophysical work in the Scoresby Sund region, East Greenland

Abstract

The fourth season of the five-year mapping programme in the Scoresby Sund region was carried out in July and August. A tent base camp was established at the head of Hurry Inlet and served as operation centre for 3 helicopters. The Norwegian sealer "Brandal", and a small cutter provided transport in the fjords. The expedition members numbered 44, comprising 16 geological two-man parties and supporting personnel. Five parties mapped in the crystalline complex of Liverpool Land and one party the Caledonian supracrustal and igneous rocks on Canning Land. Mapping of the post-Caledanian sediments in Jameson Land and southern Scoresby Land was undertaken by six parties (see Birkelund and Perch-Nielsen, this repart). Two parties mapped the eastern part of the Tertiary basalt area south af Scoresby Sund and one undertook Quaternary investigations in the central and eastern part of the Scoresby Sund region. A geophysical party carried out a terrestrial magnetometer investigation across central Jameson Land and a shipborne investigation in Scoresby Sund and Hall Bredning.
