“…Sediment between $650À626 mbs was deposited during the late Paleocene Alisocysta margarita Zone [Powell, 1992], as A. margarita is consistently present and Areoligera gippingensis abundant. Moreover, the LO of A. gippingensis at 626 mbs corresponds to upper Nannofossil Zone NP6 (early Thanetian at $58 Ma) throughout the North Sea [Bujak and Mudge, 1994;Powell et al, 1996].…”

Eustatic variations during the Paleocene‐Eocene greenhouse world

[1] We reconstruct eustatic variations during the latest Paleocene and earliest Eocene ($58-52 Ma). Dinoflagellate cysts, grain size fractions, and organic biomarkers in marine sections at four sites from three continents indicate an increased distance to the coast during the Paleocene-Eocene thermal maximum (PETM). The same trend is recognized in published records from other sites around the world. Together, the data indicate a eustatic rise during the PETM, beginning 20 to 200 ka before the globally recorded negative carbon isotope excursion (CIE) at $55.5 Ma. Although correlations are tentative, we recognize other global transgressions during Chrons C25n and C24n. The latter may be associated with Eocene Thermal Maximum 2 ($53.5 Ma) or the ''X''-event ($52 Ma). These results suggest a link between global sea level and ''hyperthermal'' intervals, potentially because of the melting of small alpine ice sheets on Antarctica, thermal expansion of seawater, or both. However, the early onset of sea level rise relative to the CIE of the PETM suggests contributions from other mechanisms, perhaps decreasing ocean basin volume, on sea level rise.

“…Mudge & Bujak (2001) found that the youngest occurrences of common and abundant Palaeoperidinium pyrophorum correspond to the lower NP6 zone in the Faeroe-Shetland Basin. However, more sporadic occurrences of this species are reported from younger Early Paleogene strata (NP9- published by Powell (1992) are based on North Sea data, and should not be expected to be completely concurrent with the high latitude ranges. However, the age evidence seems consistent enough to conclude that the Firkanten and Basilika formations on Sørkapp Land are of Early to Mid Thanetian age.…”

Are there Upper Cretaceous sedimentary rocks preserved on Sørkapp Land, Svalbard?

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.
