Biostratigraphy
dinoflagellate cyst The Department of Stratigraphy at GEUS offers academic and consultancy expertise in pre-Quaternary biostratigraphy. Our experienced staff comprises five palynologists, two micropalaeontologists and one macropalaeontologist, all educated to Ph.D. level. The Department operates a high quality micropalaeontological and palynological laboratory with the capacity to handle and process a large volume of samples. Our safety standards (due to use of hazardous chemicals) are of a particularly high level.

At GEUS, biostratigraphic analyses are performed routinely on borehole and outcrop samples. The following microfossil groups are catered for:

  • Microfossils: Foraminifera, diatoms, nannoplankton, dinoflagellate cysts and spores and pollen.
  • Macrofossils: Mesozoic ammonites and belemnites.
The Department boasts an advanced image database of our fossil specimens, facilitating identification and documentation of the taxa.

We provide routine biostratigraphic reports on an individual well basis or as multidisciplinary regional studies. Biostratigraphic data are combined with other geological disciplines, e.g. log-correlation, sedimentology, sequence stratigraphy, seismic interpretation, isotope stratigraphy and organic and inorganic geochemistry, catered to your requirements. Our biostratigraphic data are presented as range charts using the "StrataBugs" program, which is widely used by companies in the oil industry. Our clients include a range of larger energy- and oil companies.

Recent major projects carried out at GEUS involving biostratigraphic studies include:

  • Cretaceous-Palaeogene of onshore and offshore West Greenland based on combined palynological, nannofossil and foraminifera analysis and correlation with onshore and offshore Canada (hydrocarbon exploration).
  • Cretaceous-Paleocene of East Greenland correlated with wells offshore the Faeroe Islands and offshore mid-Norway (hydrocarbon exploration).
  • Upper Cretaceous - Danian nannofossil stratigraphy in chalk (Central Graben (DK, N, NL, UK) and onshore Denmark) (hydrocarbon exploration).
  • Palaeogene - Lower Neogene of the Danish North Sea (basis for a new lithostratigraphy).
  • The Miocene and Pliocene succession in the eastern North Sea Basin (mapping of aquifers for drinking water).
  • Jurassic, deep clastic reservoirs in the Central Graben area (Denmark and Norway) (hydrocarbon exploration).
  • The Triassic-Jurassic succession of onshore Denmark (CO2-storage and Geothermal energy).
In addition to the above, we also have many years experience in Upper Palaeozoic pollen and spore analysis.
