Abstract

An about 200-m long sandstone dyke cutting through the shales of the Janusfjellet Formation (Jurassic-Lower Cretaceous) has been discovered at Janusfjellet Central Spitsbergen. The palynomorph assemblage and the character of sandstone from the dyke are indicative of the Firkanten Formation of Paleocene age.
