The presumed Carboniferous, Permian and Lower Triassic sediments of Jameson Land and Scoresby Land, have been palynologically investigated. Four main assemblages are recognised which form the basis for a coarse stratigraphy. The Lower Permian Potonieisporites assemblage occurs in all palynologically productive fine-grained sediments from the Gurreholm Dai and the Mesters Vig Formations. The lowermost part of these sediments in Skeldal may be of latest Carboniferous age. An Upper Permian Vittatina assemblage characterises the lower part of the Foldvik Creek Formation. An Upper Permian / Lower Triassic Protohaploxypinus assemblage occurs in the upper part of the Foldvik Creek Formation. The Lower Triassic Wordie Creek Formation contains a Taeniaesporites assemblage. The preliminary investigation suggests a gradual change in the palynoflora. This again points to presence of a complete or almost complete sedimentary transitional sequence from the Upper Permian to the Lower Triassic.
