Abstract:
The presence of abundant age-diagnostic dinoflagellate cysts in Ocean Drilling Program (ODP) Hole 913B (Leg 151), Deep Sea Drilling Project Hole 338 (Leg 38) and ODP Hole 643A (Leg 104) has enabled the development of a new biostratigraphy for the Eocene-Oligocene interval in the Norwegian-Greenland Sea. This development is important because the calcareous microfossils usually used for biostratigraphy in this age interval are generally absent in high latitude sediments as a result of dissolution. In parallel with this biostratigraphic analysis, we developed a magnetic reversal stratigraphy for these Norwegian-Greenland Sea sequences. This has allowed independent age determination and has enabled the dinocyst biostratigraphy to be firmly tied into the global geomagnetic polarity timescale (GPTS). The relatively high resolution of this study has enabled identification of dinoflagellate cyst assemblages that have affinities with those from the North Sea and the North Atlantic, which allows regional correlation. Correlation of each site with the GPTS has also allowed comparison of the stratigraphic record preserved in each drill-hole. Hole 913B is the most complete and is the best-preserved record of the Eocene and Oligocene in the Northern Hemisphere high latitudes, and can serve as a reference section for palaeoenvironmental reconstructions of this age interval.
