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).

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, 189, 7-10. https://doi.org/10.34194/ggub.v189.5148 _______________ The year 2000 was unusual in that it lacked major field activity directly involved with the systematic geological mapping of Greenland. However, field activities were again many and varied, including a successful highresolution seismic survey offshore central West Greenland, and a joint Geological Survey of Denmark and Greenland (GEUS) – Danish Lithosphere Centre (DLC) project centred on Kangerlussuaq in southern East Greenland. Of the Survey’s 354 personnel, 93 were allocated to Greenland-related activities (Table 1). The Greenland level of activity in 2000, both in Copenhagen and in the field, thus compared favourably with that of 1999.

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.

In 1991 a three year research project was initiated by the Geological Institute, University of Copenhagen with financial support from the Ministry of Energy, the Danish Natural Science Research Council and the Carlsberg Foundation. The 'Wandel Sea Basin: basin analysis' project was carried out in collaboration with the Geological Survey of Greenland and included field work in North Greenland; in eastern Peary Land in 1991 and Amdrup Land in 1993 (Fig. 1; Hakansson et al., 1994). The project is a continuation of earlier investigations in the Wandel Sea Basin carried out during geological mapping of North Greenland by the Geological Survey of Greenland in 1978–1980 and during later expeditions to the area (e.g. Hakansson, 1979; Hakansson et al., 1981, 1989, 1991, 1994). Hydrocarbon related studies of the Wandel Sea Basin were continued during the 1994 field season (Stemmerik et al., this report).

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.

General Overview ◽  
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).

The main field activity of the Survey in 1978 was a study of the geology of North Greenland (fig. 1). This was the first summer of a three year project which aims at a geological synthesis of the whole region together with the compilation of two 1:500000 geological maps. Significant additions to the geological knowledge of the area included the discovery ol an extensive Proterozoic basalt province, an extension of the known distribution of the late Proterozoic to Silurian strata, and of the late Palaeozoic to Tertiary Mesozoic sequences of the Wandel Sea Basin. The field work has been undertaken in cooperation with the Geodetic Institute, establishing a set of ground central points for the preparation of topographic maps of northern Greenland. These maps will be based on a new set of aerial photographs which were taken during the summer. The Danish Air Force using a Hercules aircraft flew in the group of 32 geologists and surveyors and their equipment to Station Nord. Geological studies and surveying went according to plan, in spite of more snow cover than usual in most of Peary Land.

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.
