A joint programme has been embarked upon with the Geological Survey of Canada to use the palaeomagnetism of basic dykes as a possibie correlation parameter between rocks of north-eastem Canada and those of West Greenland. As part of this, programme field work during the summer was concentrated within the early Precambrian craton of West Greenland where sampling of Precambrian basic dykes was undertaken in three areas, namely the Fiskenæsset, Søndre Strømfjord and Godthåb areas.

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.

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.

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).

Field Activity

In 1975 the Danish Natural Science Foundation (SNF) and the Geological Survey of Greenland (GGU) initiated an investigation of the microplankton (dinoflagelIate cyst) of the Cretaceous and Tertiary sediments in central West Greenland. The purpose of this investigation is the establishment of a dinoflagelIate stratigraphy based on samples from measured sections to assist in a basin analysis. SNF provided the funds for the establishment of a laboratory for palynological preparation and investigation. They also funded a Leitz Orthoplan microscope with a Leica camera for the study of the microplankton, and two of the six Honda ATC 90 motor tricycles that facilitated the field work. The main field activity in 1975 has been outlined by Croxton (this report). As mentioned by Schiener & Henderson (1975), seven weeks field work were carried out in 1974 by the writer and T. Jürgensen. In 1974 ten sections (M1 - M10) totalling 2670 m of sediment were measured and 201 samples were collected. T. Jürgensen also measured a series ofsections (T2 -T14). In 1975 nineteen sections(M11-M29) were measuredand 837 samples were collected (see fig. II for localities).

During the regional mapping programme in the Godthåbsfjord region (see Bridgwater & McGregor, this report p. 39) D.B. and V.R.M. spent 14 days in the Isua area near the margin of the Inland lce, approximately 150 km north-east of Godthåb, in order to examine the Isua supracrustal suite and to determine its relation to the surrounding gneisses and to the geology of Godthåbsfjord.

Geological Evolution

During the past decade the Geological Survey of Denmark and Greenland (GEUS) has carried out two major resource evaluations in the Precambrian basement terranes of South and West Greenland in order to locate potential areas of mineral deposits (Steenfelt et al. 2000, 2004; Stendal & Schønwandt 2003; Stendal et al. 2004). Based on geological field work and geochemical and geophysical data, these evaluations have assessed the interplay between the magmatic, tectonic and metamorphic evolution in the study areas and their mineralising events. As a result of the second of these evaluations it is now possible to outline a succession of mineralising events in the northern part of the Nagssugtoqidian orogen and in the Disko Bugt area of central West Greenland (Fig. 1), and relate them to the general Archaean and Palaeoproterozoic geological evolution of this region. However, uncertainties still exist concerning the age and detailed setting of many epigenetic mineralisations.

The background for the Geological Survey of Greenland's (GGU's) hydrocarbon-geological activities was briefly outlined in the Report of Activities for 1989 (Stemmerik et al., 1990a). In that report it was intimated that a shift of emphasis in hydrocarbon-geological activities was under way, not only from onshore to offshore but also from East to West Greenland (Fig. 1). 1990 saw this shift take more concrete form. Thus field work in East Greenland was limited to minor projects that focus on diagenesis and reservoir properties of siliciclastic sediments. All other projects onshore East Greenland have reached or are entering into final report stage

Supracrustal Belt

The Isua supracrustal rocks of West Greenland have been in international focus ever since their earliest Archaean age was demonstrated in the early 1970s. For years they were highlighted as the Earth's oldest rocks. Although the 'oldest rocks' tag has now passed elsewhere, the well preserved Isua supracrustal sequence still attracts research projects directed towards understanding the Earth's history. This note refers to one such project, carried out by the Geological Survey of Greenland in collaboration with Centre de Recherches Petrographiques et Geochimiques, Nancy, France, concerning the recognition of cosmic material in the Isua rocks. Field work in 1993 concentrated on detailed sampling of a chert sequence.

This paper presents results of the aeromagnetic survey and discusses the correlation of the measured data with the previously mapped surface geology. The project was financed by the Government of Greenland and managed by the Geological Survey of Denmark and Greenland. Sander Geophysics Ltd., Ottawa, Canada, was selected in April 1999 as the contractor for the project through a European Union opentender procedure.

Geology of Greenland Survey Bulletin, 183, 46-56. https://doi.org/10.34194/ggub.v183.5204 _______________ In the last few years there has been renewed interest for petroleum exploration in West Greenland and licences have been granted to two groups of companies: the Fylla licence operated by Statoil was awarded late in 1996; the Sisimiut-West licence operated by Phillips Petroleum was awarded in the summer of 1998 (Fig. 1). The first offshore well for more than 20 years will be drilled in the year 2000 on one of the very spectacular structures within the Fylla area. To stimulate further petroleum exploration around Greenland – and in particular in West Greenland – a new licensing policy has been adopted. In July 1998, the administration of mineral and petroleum resources was transferred from the Danish Ministry of Environment and Energy to the Bureau of Minerals and Petroleum under the Government of Greenland in Nuuk. Shortly after this, the Greenlandic and Danish governments decided to develop a new exploration strategy. A working group consisting of members from the authorities (including the Geological Survey of Denmark and Greenland – GEUS) made recommendations on the best ways to stimulate exploration in the various regions on- and offshore Greenland. The strategy work included discussions with seismic companies because it was considered important that industry acquires additional seismic data in the seasons 1999 and 2000.
