INTRODU CTION
Iceland is one of the geological objects on the Earth, studies of
which promise a key for understanding the glohal geological pro-
cesses. Lying on the continuation of the Mid-Atlantic Ridge and
accessible for detailed land investigations, Iceland attracts the at-
tention of geologists and geophysicists from various countries. In
1970—1973 the USSR Academy of Sciences undertook systematic
investigations in Iceland and the North Atlantic by organizing an
interdisciplinary geologic-geophysical expedition to the island and
cruises of the research vessels “Academic Kurchatov” and “Mikhail
Lomonosov” to the neighbouring waters.
In 1972 the expedition participated in the international seismic
investigations NASP (North-Atlantic Seismic Project) aimed at the
studies of the crustal structure by deep seismic sounding method in
Iceland, Iceland-Faeroe Ridge and between the Faeroe, Shetland and
Rritish Isles.
The present paper deals with some of the results of NASP in the
areas of Iceland, Iceland-Faeroe Ridge and Faeroe- Shetland region.
Previous Investigalions
Seismic investigations of the crustal structure of Iceland were
systematically carried out by Pálmason (1). In the Atlantic ocean
south, east and north of the island the crust was studied by Ewing
