Spitsbergen is located in the northwestern corner of the Eurasian Plate in a key area for reconstruction of the geological history of the North Atlantic and Arctic regions. According to modern interpretations, Spitsbergen was assembled during the Caledonian orogeny from four different terraines with their own pre-Caledonian history. They are separated by N-S faults and a Devonian graben, and overlain by Carboniferous to Tertiary platform sediments. The Tertiary fault belt as result of Atlantic opening occures around the western shore of the archipelago. The marine part of the area can be subdivided into three tectonic units – the typical shelf in the southeastern and two continental slopes: in the north and in the west.
illustrate the geological position of Spitsbergen and its varied
composition together with surrounding shelf, a set of maps in 1:1 000 000
scale has been chosen as the most convenient one. The introduced set of
maps is result of summarized data, which were obtained by geologists from
different countries. A.K. Orvin made the first map in 1936. Norwegian
Polar Institute in 1960 and in 2002 published the more recent maps (Winsnes,
Dallmann et al., 2002). The diferrenc of represented ones is that the sea
floor bedrock geology around the archipelago is shown in the same legend
as on the land. Geophysical results as seismic profiles and aeromagnetic
observations carried out mainly by Norwegians and Russians, were used for
the marine part of these maps.
technology has made it easy to incorporate the new data and connected
materials into the maps. The geological map of Spitsbergen and the
surrounding shelf with text description is a part of the set of maps,
which additionally includes geomorphological and tectonic ones. The maps
of Mineral and Quaternary deposits are nearest targets for the complete
set. The completion of the prepared maps by collected data and organises
them, as real Information System is the main future target.
