Abstract
The Geological Survey of Greenland (GGU) continued activities during 1974 in accordance with its role as the official government department of the Ministry for Greenland responsibie for all practicai and scientific aspects of geological investigation. A total of 121 people travelled to Greenland in connection with a variety of geological, geophysical, glaciological and hydrogeological projects in 12 areas (fig. 2). Interest in the mineral and hydrocarbon potential of Greenland gained new impetus during 1974 as a result of the general energy crisis. GGU has continued to advise the Ministry on marters concerning concession rights for exploration and extraction of mineral and hydrocarbon resources and, together with the geological institutes of the University of Copenhagen, supported the initiative taken by the Danish Natural Science Research Foundation (Statens Naturvidenskabelige Forskningsråd) with respect to new investigations in Greenland related to economic potential. Interest in the hydrocarbon potential of the West Greenland shelf culminated during 1974 with the Ministry of Greenland inviting applications for concessions in three areas. By the closing date 22 formal applications were received. Details concerning the allocation of concession areas were announced in April 1975. Recent developments in this field in which GGU has advised the Ministry are summarised by Henderson (this report).

Examination of suitable sites for proposed uranium mining has taken place in the Kvanefjeld area of South Greenland, while a group of Survey geologists have again been involved in prospecting for radioactive minerals in East Greenland
The number of permanent staff employed by GGU in Copenhagen increased substantially during 1974. 32 geologists and chemists were employed, together with 61 administrative, laboratory, technical and maritime personnel
Summary
The main areas of GGU activity in Greenland during the June-September field season of 1974 are shown in fig. (a) geologieal mapping (b) Quaternary investigations (c) geophysical surveys (d) geochemical programmes (e) economic investigations (f) special topics (a) Geological mapping was undertaken in North Greenland and in several areas in West Greenland. (d) Geochemical programmes were concemed with prospecting activities in East and South Greenland, and the continued assessment of the ecological effects of the lead and zinc mining at Marmorilik, central West Greenland (Nielsen & Steenfelt; Asmund). (e) In addition to the geophysical and geochemical prospecting discussed above, Survey geologists were engaged in sedimentological investigations af the central West Greenland basin relevant to assessment of hydrocarbon potential (Schiener & Henderson). (f) In connection with proposed future mapping activities in North Greenland a party of geologists measured reconnaissance profiles through Lower Palaeozoic sediments in southem Peary Land (Peel & Christie). Special sedimentological studies were made of Mesozoic strata in Jameson Land and north of Kejser Franz Josephs Fjord, central East Greenland, with a view to elucidating the conditions under which the rocks were deposited (Birkelund & Heinberg; Surlyk & Clemmensen)
