Digital outcrop model of the Landnørdingsvika cliff in Southwestern Bjørnøya. The profile shows a spectacularly exposed outcrop of the Mid-Late Carboniferous time, it is tilted down towards the west due to a large controlling normal fault, mapped on seismic offshore Bjørnøya. The base of the succession shows alluvial red-bed sediments (shales and conglomerates) with interbedded white shallow marine sandstones (Landnørdingsvika Fm) transitioning upwards into marine sandstones and later dominating marine carbonates (Kapp Kåre Fm). The succession shows the interplay between mid-late Carboniferous sea-level fluctuations (mainly controlled by ice-sheets on the southern hemisphere) and local/regional extensional tectonics and is a good outcrop analogue to the Carboniferous-Early Permian deposits offshore in the basins of the Barents Sea, which have historically targeted for hydrocarbon exploration.
