The Department of Stratigraphy at GEUS offers research and consultancy in pre-Quaternary biostratigraphy.
Our experienced staff comprises five palynologists, one micro-palaeontologist 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 are of a particularly high level.
Biostratigraphic analyses are performed routinely on borehole and outcrop samples. The following fossil groups are covered:
- 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, seismic interpretation, sedimentology, sequence stratigraphy, isotope stratigraphy and organic and inorganic geochemistry.
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 several larger energy- and oil companies.
