Paleogene formations on eastern Sørkapp Land contain common, reworked, Middle and Late Cretaceous terrestrial and marine microfloras. This observation questions the Late Cretaceous age reported for the Firkanten Formation in the Øyrlandet Graben on western Sørkapp Land, as the pollen and spores reported from this graben may not be in situ. The present palynostratigraphic data from the eastern Sørkapp Land suggest that the Firkanten and Basilika formations were deposited in a relatively short time-period during the Early to Mid Thanetian. The youngest Cretaceous deposits documented from the Carolinefjellet Formation in eastern Sørkapp Land are of Late Albian age.
