The Faroe Islands and adjacent areas
A thick and extensive sheet of Paleogene flood basalts (Faroe Volcanic Group (FVG)) dominates this area, extending over a wide area from the seawards-dipping reflectors (SDRs) at the oceanic margin to the Faroe-Shetland Basin (FSB) and the Wyville-Thomson Ridge, cropping out extensively at the sea-floor (Figs 171 & 176). In most areas, the pre-FVG (‘subbasalt’) section is almost unknown due to difficulties in seismic interpretation below the basalts and very limited penetration by wells. To the east and SE of the Faroe Islands, the upper surface of the FVG forms a relatively flat platform (Faroe Platform), dipping gently SE. To the south and SW of the Faroe Islands, however, it has been deformed by post-FVG tectonics into a series of basins and highs, with thick overlying Cenozoic sediments in some areas. These areas are summarized here, approximately from south to north (Figs 180 & 181).
