Field mapping in the Scoresby Sund region, East Greenland

The third season, 1970, of the five year mapping programme in the Scoresby Sund area lasted slightly more than two months. As in the previous years the expedition was based on a special polar vessel which carried two Bell helicopters. The ship used was the 2675 ton "Perla Dan", which with a crew of 25 supported 3 smaller boats. The expedition members numbered 43, comprising 16 geological two- or three-man teams, and supporting personnel. The geological teams were divided into several working groups. Eight two-man parties worked in the crystalline complex in the inner fjord region around Rødefjord and on Milne Land. One party mapped the upper Palaeozoic sediments at Rødefjord. Five parties mapped the Mesozoic rocks on Milne Land and on south-eastern Jameson Land (see Birkelund, this report); three of these parties, in addition to mapping, undertook special palaeontological investigations along the west coast of Rurry Inlet and were financiaIly supported by the Carlsberg Foundation. One party worked in the Tertiary basalt on southeastern Milne Land and north-west Gåseland, and one party undertook a Quaternary geological investigation in the central part of the inner fjord zone.
