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.

A Cretaceous (Aptian) to Cenozoic composite oxygen isotope curve is presented and correlated to eustatic records and to global tectonic events. The curve was built using deep water benthonic foraminifera from DSDP/ODP sites. In addition, well-dated outcrop and subsurface whole rock samples were used. This composite record provides insight about the evolution of deep-water temperatures and/or ice volume changes from the Aptian to the present. Two important observations can be made from the isotope record. First, three low-frequency isotope cycles are recognized, encompassing most of the Upper Cretaceous (named Uki), most of the Paleogene (named Pi) and most of...
