A continuous basin is present offshore, with a maximum thickness varying with latitude from less than 2 km to more than 10 km. The age of the sediments is unknown, but they probably range from Tertiary down to at least Jurassic, and there is some evidence for Palaeozoic ages. The offshore basin is separated by a basement ridge from the onshore basin, and the offshore extension of the Tertiary volcanics is smaller than previously thought. Petroleum potential of the area is good, but limited by a scarcity of structural traps and by severe ice conditions.
