Eight depositional sequences are recognized within marine Paleogene strata of the Tremp Basin (Southern Pyrenean Foreland Basin). Geometry and distribution of the depositional systems are mainly controlled by tectonics and relative sea-level changes. Carbonate systems dominate during sea-level highstands, siliciclastic systems during sea-level lowstands.
Biostratigraphic boundaries inherently tend to correspond to sequence stratigraphic surfaces (condensed sections, intervals of non-deposition). Biostratigraphic correlations provide only a rather loose framework and should not be overstretched. In marine Paleogene units of the Southern Pyrenees, their resolution is generally not sufficient to identify individual global eustatic 3rd order cycles without ambiguities.

Mesozoic and Cenozoic Sequence Stratigraphy of European Basins
Mesozoic and Cenozoic Sequence Stratrigraphy of European Basins - This project was designed to build a documented chronostratigraphic and outcrop record of depositional sequences calibrated across European Basins. Data on standard stages, magnetostratigraphy, and geochronology integrated with high resolution biostratigraphy calibrate the stratigraphic position of depositional sequence boundaries. Higher order eustatic sequences show a significant increase in the number identified. A good portion of the European Mesozoic and Cenozoic succession is set in a sequence stratigraphic context with a better stratigraphic record of its bonding surfaces.
