Field investigations aimed at the produetion of a 1:500 000 map sheet of the Thule distriet were continued during August and early September. The unusuaIly poor weather conditions and the premature arrival of the winter's snowfall, reduced the season to some 20 effective working days. The field work was in two parts. At the beginning of the season a Jet Ranger helicopterwas chartered at Thule Air Base and four days were spent investigating nunatak and inland areas north of Savigsivik and Kap York and at the heads of Wolstenholme Fjord, Olrik Fjord and Inglefield Bredning. The second part was an investigation ofthe Proterozoic Thule Groupon Herbert ø, Northumberland Ø and Hakluyt Ø. Transport for this phase wasa locally hired boat from Avatak Henson of Moriussaq. Certain logistic support was supplied to H. R. Cooke who visited the Thule district at the end of the field season to assess the economic potential of various minerallocalities. Kurt Thomsen ably assisted both in Cooke's and the author's field programmes.

The programme of field investigations in the north of the Ivisartoq region begun in 1981 by Chadwick & Crewe (1982) was continued in 1982. Julia Park began mapping the Taserssuaq granodiorite, its host rocks and the Ataneq fault in the north-west. Dur team was joined by D. Bellur, Geological Survey of India, nominally as an assistant. In this report we present only summary notes of new findings relevant to the interpretation of the geometry and chronology of this segment of the Archaean crust in southern West Greenland. We use the established terminology for the Archaean rocks of the Godthåbsfjord region.

The field mapping of the Precambrian crystalline basement and overlying Thule Group of the Thule district aimed at the production of a 1:500000 map sheet between 75°15'N and 78°N was continued in July and August (fig. 5). The field work was split up, due to the varying availability of transport facilities, into three phases. (1) The charter of a Bell 204 helicopter from Thule Air Base enabled mapping in western Inglefield Land, and in the nunatak terrain of Prudhoe Land and Melville Bugt. (2) Investigation of the outer coast of western Melville Bugt was carried out with the aid of GGU cutter K. J. V. Steenstrup. (3) Detailed stratigraphical work in the middle and upper part of the Thule Group was based on foot traverses from Thule Air Base.

Proterozoic Basement

One of GGU's major field activities in 1991 took place in July and August in the Disko Bugt region of central West Greenland. This was the third year of field investigations under the 'Disko Bugt Project', planned for 1999–1992, with one summer's break in 1990. The project spreads over various activities and over two very different geological provinces: the Archaean-Proterozoic basement east and north-east of Disko Bugt, and the onshore part of the Cretaceous-Tertiary basin in the west, on Disko and the western part of Nugssuaq (Fig. 1). In 1989, the second year of the project, work was concentrated in the eastern basement part of the study area, and in 1991 this work was brought to conclusion. In 1992 field work (including a shallow core drilling campaign) will be concentrated in the sediments and volcanics on Nugssuaq and Svartenhuk Halvø to the north. The main aim of the Disko Bugt Project is to provide a background for the evaluation of the economic potential of the regional mineral resources, mainly in the Precambrian basement, and the hydrocarbon potential of the neighbouring basin offshore (see Kalsbeek, 1989. 1990).

Geology of Greenland Survey Bulletin, 183, 39-45. https://doi.org/10.34194/ggub.v183.5203 _______________ The Upernavik 98 project is a one-year project aimed at the acquisition of information on mineral occurrences and potential in North-West Greenland between Upernavik and Kap Seddon, i.e. from 72°30′ to 75°30′N (Fig. 1A). A similar project, Karrat 97, was carried out in 1997 in the Uummannaq region 70°30′–72°30′N (Steenfelt et al. 1998a). Both are joint projects between the Geological Survey of Denmark and Greenland (GEUS) and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, and wholly funded by the latter. The main purpose of the projects is to attract the interest of the mining industry. The field work comprised systematic drainage sampling, reconnaissance mineral exploration and spectroradiometric measurements of rock surfaces.

Geology of Greenland Survey Bulletin, 191, 133-143. https://doi.org/10.34194/ggub.v191.5141 _______________ Project Qaanaaq 2001, involving one season’s field work, was set up to investigate the mineral occurrences and potential of North-West Greenland between Olrik Fjord and Kap Alexander (77°10´N – 78°10´N; Fig. 1). Organised by the Geological Survey of Denmark and Greenland (GEUS) and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, the project is mainly funded by the latter and has the overall goal of attracting the interest of the mining industry to the region. The investigated region – herein referred to as the Qaanaaq region – comprises 4300 km2 of ice-free land centred on Qaanaaq, the administrative capital of Qaanaap (Thule) municipality. Much of the region is characterised by a 500–800 m high plateau capped by local ice caps and intersected by fjords and glaciers. High dissected terrain occurs in Northumberland Ø and in the hinterland of Prudhoe Land where nunataks are common along the margin of the Inland Ice.

After the successful completion of the 1993 field work and drilling programme in the Marraat area on western Nuussuaq (Fig. 1), including a subsequent logging and geophysical programme (see Christiansen et al., 1994a, b; Dam & Christiansen, 1994), a new picture of onshore ex­ploration opportunities has started to develop. Previously the onshore basins were only considered to have a minor exploration potential, if any at all. However, the Disko-Nuussuaq-Svartenhuk Halvo region has been an important study area because many of the key parameters (sedimentological, stratigraphical and organic geochemical data from the excellent outcrops) may be obtained for predicting the distribution of reservoir and source rocks in the neighbouring major offshore basins in North-West and West Greenland (Christiansen et al., 1992, I994c).

North Greenland

The Geological Survey of Greenland (GGU) initiated in 1964 a 1:500000 mapping programme to produce a general overview of the onshore geology of all the ice-free areas of Greenland. So far 10 of a total of 14 planned map sheets have been published, and one additional sheet for which field work has been completed is under compilation. Most of Greenland is therefore now covered by map sheets of this series and only three areas remain to be covered: in North-West Greenland (sheet 6), in eastern North Greenland (sheet 9) and in East Greenland (sheet 11). Eastern North Greenland (map sheet no. 9; Fig. 1) is the target of the present project, with planned field work from 1993–1995. The first season (1993) was used for logistical preparation and geological reconnaissance in advance of the more intensive field work in the two following seasons (1994–95).

Geology of Greenland Survey Bulletin, 186, 65-72. https://doi.org/10.34194/ggub.v186.5217 _______________ The Isukasia region of southern West Greenland contains the Earth’s oldest known supracrustal rocks (the c. 3.8–3.7 Ga Isua greenstone belt: Appel et al. 1998) and well-preserved mafic dyke swarms (Inaluk and Tarssartôq dykes: Nutman et al. 1983). This report describes field investigations of the dykes carried out in 1999 as part of the Isua Multidisciplinary Research Project, and summarises current knowledge of the dykes. The project was initiated in 1997 with the aim of coordinating a detailed reinvestigation of this geologically important region. Fifteen members of the group were involved in field work in 1999 and this article represents only one aspect of the work.

The 1980-1981 field work in Precambrian basement rocks for the Fiskefjord map sheet was continued in 1983. V. R. McGregor mapped granulite facies gneisses south of outer Fiskefjord in the south-western part of the map sheet area. The author worked inland between Godthåbsfjord and Fiskefjord from the eastern map sheet boundary at 50°54'E westwards to 51°45'E (fig. 22) and some notes concerning the lithologies, geometry and geochronology of this area are presented below. The GGU cutter K. J. V. Steenstrup and a Jet Ranger helicopter on weekly charter from Godthåb provided logistic support for the two Fiskefjord teams and for four teams mapping in the Ivisårtoq area (see Brewer et al., this report) as well as for the GGU glaciological station at Qamanârssûp serrnia.
