On the peninsula between Ekmanfjorden and Dicksonfjorden, Spitsbergen, Devonian sandstones are overlain unconformably by a series of Permo-Carboniferous rocks. These consist of 200 meters of limestone, with a thin basal conglomerate and frequent layers of nodular chert, a succession of 300 meters of beds of dolomite, limestone, gypsum, and anhydrite, and 150 meters of chert. Dolerite sills outcrop in the area and are more widespread than previously mapped. They occur at a constant stratigraphic level, but are not continuous. The major lithologic horizons can be recognized in nearby areas, and a tentative correlation is made, which can probably be extended later.
