Field activities in Greenland by the Geological Survey
of Denmark and Greenland (GEUS) in 2001 were again
many and varied. They included economic investiga-
tions of crystalline basement and sedimentary rocks in
North-West Greenland, and a systematic mapping pro-
ject combined with resource evaluation in the bound-
ary zone of the Nagssugtoqidian and Rinkian mobile
belts of central and southern West Greenland. In addi-
tion, studies of the Vendian to Lower Palaeozoic suc-
cessions in North-East Greenland and of the Palaeogene
sediments of central East Greenland were carried out,
a major aeromagnetic survey was flown in central West
Greenland, and investigations of Holocene lake sedi-
ments in southern West Greenland were continued.
In 2001 the proportion of GEUS human resources
committed to Greenland activities compared favourably
with that in preceding years, although financial resources
allocated to Greenland have experienced a marked
downward trend over recent years (Table 1). The lat-
ter reflects primarily the decrease in Greenland field activ-
ities of the Danish Lithosphere Centre (DLC), which is
administratively attached to GEUS, as well as a reduc-
tion in funding from external sources. Despite their
much reduced field activities in Greenland, a significant
proportion of DLC's research in 2001 was still related
to Greenland. An additional factor influencing the fig-
ures for expenditure quoted in Table 1 is of a techni-
cal nature in the sense that although aeromagnetic
surveys were flown in both 1999 and 2001, the con-
tractual expenses of acquisition were included in the
figures for external funding in 1999, but not in the fig-
ures for 2001.
The primary source of the Survey's funding is the
Finance Law appropriation from the Danish State. The
proportion of this grant allocated to Greenland-related
activities is based on annual work programmes planned
in consultation with the Greenland authorities, in par-
ticular the Bureau of Minerals and Petroleum (BMP) of
the Government of Greenland. The planned activities
are approved by the Board of GEUS, on which BMP is
represented.
External sources of funding for Greenland activities
in 2001, as in previous years, came primarily from BMP
and from Danish and international research founda-
tions of which the most important are the Danish Natural
Science Research Council, the Carlsberg Foundation,
the Commission for Scientific Research in Greenland and
the European Union. DLC is funded by the Danish
National Research Foundation.
Regional geology and mapping
Systematic mapping was undertaken in 2001 in the
Aasiaat region of central West Greenland, located at
the transition between the Rinkian and Nagssugtoqidian

Proterozoic mobile belts (Fig. 1, A). This project is
aimed at the production of two 1:100 000 geological map
sheets, and is an extension of the field work in 2000
on the Ussuit map sheet of the Nordre Strømfjord area
immediately to the south.
Field work for the Isua Multidisciplinary Research
Project in the Isukasia area of southern West Greenland,
focused on the `Earth's oldest rocks', was completed in
2001 (Fig. 1, G); this was the last summer of a planned
series of field seasons involving a large number of
Danish and international scientists.
The studies of the Vendian to early Palaeozoic rocks
of Ella Ø and surroundings in North-East Greenland
were continued in 2001 (Fig. 1, J); these are part of a
continuing project investigating the passive margin suc-
cession of the Laurentian continent. Studies of the
Palaeogene sediments of central East Greenland form
part of regional petroleum geology investigations, and
are described below.
Mineral resources
A field party visited the Qaanaaq region of North-West
Greenland (Fig. 1, M) in 2001, focused on an assess-
ment of the economic potential in the basement crys-
talline rocks as well as the overlying Mesoproterozoic
sediments of the Thule Supergroup.
A regional aeromagnetic survey financed by BMP
was carried out in central West Greenland covering a
broad onshore and offshore region centred on
Svartenhuk Halvø (Fig. 1, C). A total of 70 000 line km
of high quality data was acquired. Regional aeromag-
netic data coverage now extends from the southern tip

of Greenland northwards along the entire western coast
as far as latitude 72°12´N.
In conjunction with the systematic regional mapping
programme in the Aasiaat region of central West
Greenland, a resource assessment of the region between
Nuussuaq and Maniitsoq was undertaken in 2001 (Fig.
1, B). Economic studies were carried out by field teams,
and included investigations of the kimberlitic rocks in
the Sisimiut­Kangerlussuaq region.
Other activities have included sample collections aimed
at ground control of the hyperspectral data acquisition
carried out in 2000 in central East and North-East
Greenland. In addition, localities in South-East, South and
southern West Greenland (Fig. 1, N) were visited in order
to assess the potential for ornamental stone quarrying.
Petroleum geology
Most petroleum geology activities undertaken in 2001
were in preparation for the licensing round planned for
mid-2002. The focus was mainly on promotion of the
exploration opportunities in the licensing round area
between 63° and 68°N, together with the launching of
new seismic and geological projects.
Special mapping projects have been directed towards
the Palaeogene sediments offshore southern West Green-
land (Fig. 1, F) and the offshore area with volcanic rocks
at the seabed north of latitude 68°N. A geohazard study
covering the major part of the offshore licence area
between 63° and 68°N was carried out for BMP in 2001.
A major source rock project involving collection and
comparison of mid-Cretaceous source rocks from the
interior of North America, the Canadian Arctic and the
Baffin Bay ­ Davis Strait region was initiated. This is
aimed at advancing the understanding of potential petro-
leum systems offshore West Greenland.
In continuation of earlier field work in the pre-basaltic,
Cretaceous and Paleocene sediments of the Kanger-
lussuaq region in East Greenland, a field party visited
the Kap Dalton and Savoia Halvø areas (Fig. 1, I); here
the youngest pre-basaltic, and oldest post-basaltic sed-
iments are exposed. Relationships at these localities are
of particular importance for the understanding of pre-
drift North Atlantic geology.
General scientific activities
Sampling of Holocene lake sediments has been carried
out for a number of years in West Greenland, with the
objective of assessing the influence of increased global
warming on the sensitive Arctic ecosystems. These activ-
ities were continued in 2001, with sampling in south-
ern West Greenland (Fig. 1, E). Strong local climate
gradients exist between the coast and the Inland Ice,
and the lakes preserve important signals relating to
Holocene environmental conditions.
In order to investigate indications of thinning of the
Inland Ice in South Greenland, GEUS has installed
instrumentation to monitor one of the major outlet glac-
iers (Sermilik Bræ) from the Inland Ice in the Narsaq
region (Fig. 1, H).
A field team collected samples of frozen peat on
Carey Øer in order to study the early dispersion of
heavy metals in North-West Greenland (Fig. 1, O
1
). The
same team collected submarine lake sediments in South
Greenland, as part of a project to evaluate sea-level
changes (Fig. 1, O
2
).
In November 2000, a major rock fall occurred on the
south coast of Nuussuaq near Paatuut (Fig. 1, D). It
was registered on seismic stations in West Greenland
and at Summit on the Inland Ice, and triggered a tsunami
in the Vaigat strait which caused damage at coastal set-
tlements, but no loss of life. The Survey undertook
studies of the geometry and volume of this rock fall,
and assessed the risk of additional rock falls in the
region.
DLC carried out seismological research in southern
Nares Strait in North-West Greenland as part of a
German­Canadian geoscience cruise (Fig. 1, P) and
continued the GLATIS and NEAT projects including the
monitoring of 11 temporary broad band seismological
earthquake stations located throughout Greenland
(Fig. 1, Q).
GEUS and higher education
The Survey, together with DLC, plays an active role in
earth science university education with GEUS staff sci-
entists and research professors being involved in stu-
dent training for higher degrees. Close co-operation
with Danish and foreign universities and research insti-
tutions is fostered, and students involved in Green-
land/North Atlantic-oriented projects often take part in
Survey-sponsored field work. In 2001, dissertations on
Greenland-related subjects were submitted to the
Universities of Copenhagen and Aarhus, Denmark for
degrees at M.Sc. (Danish cand.scient.) and Ph.D. lev-
els (see list of publications concluding this volume).

Publications
A complete list of geoscientific publications on Green-
land issued by the Survey is found in the Catalogue of
Greenland publications and data, which is also avail-
able on the web (for web address, see below). A data
directory specifying the range of data and services avail-
able at the Survey covers various databases, map, sam-
ple and drill-core archives, bibliographic and library
facilities, including unpublished maps and reports from
the Survey's own activities and those of industry. Indexes
covering projects, authors and selected topics are
included in the catalogue.
The main part of the Survey's Greenland publications
is printed in three series: a peer-reviewed bulletin series
(Geology of Greenland Survey Bulletin), a peer-reviewed
map series (Geology of Denmark and Greenland Map
Series) and an open-file report series in English or
Danish (Danmarks og Grønlands Geologiske Under-
søgelse Rapport) that is not subject to outside referee-
ing or central editing. During 2001, two bulletins and
23 reports relating to Greenland geoscience were
released to the public (a small number of reports are
classified). In addition, two geological map sheets in
the national map sheet series were published as well
as two special maps. The two bulletins published are
multi-article volumes containing 33 papers; in half of
these GEUS staff members are authors or co-authors.
About 50 scientific papers on Greenland and surrounding
seas were published in 2001 in external outlets. These
international publications document the results of exten-
sive GEUS field investigations and associated activities
in Copenhagen, including those of DLC and research
partners in surveys and geological institutes elsewhere
in the world (see list of publications concluding this vol-
ume).
An important role of the Survey is to provide up-to-
date geoscientific and legislatory information to the
petroleum and mining industries. Hence two newslet-
ters, the GHEXIS Newsletter and MINEX, launched over
a decade ago, are published jointly by GEUS and BMP.
One issue of GHEXIS and three issues of MINEX were
published in 2001.
The demand for digital versions of geoscientific data
is increasing rapidly, and the Survey is meeting this
challenge by releasing geological information, maps
and data on CD-ROM. Three CD-ROMs were issued in
2001. The GHEXIS and MINEX newsletters have been
available on the GEUS and BMP websites for several
years; however, two new sites were developed in 2001,
GHEXIS Online and MINEX Online (for web addresses,
see below). GHEXIS Online is fully developed and now
provides information on licensing policy, geology,
hydrocarbon potential, available data, and operational
conditions in connection with the licensing round off-
shore West Greenland in 2002, in addition to the GHEXIS
Newsletter. MINEX Online also provides information
on licensing policy and operational conditions.
