Integrated stratigraphy of the Turonian Stage, northwestern Europe
1 : University of Portsmouth
The Turonian chalk succession present in the Anglo-Paris Basin (France, UK) provides an expanded representation of the stage, albeit with significant condensation of the upper Turonian with the development of hardgrounds. The succession yields a high-resolution carbon isotope curve and detailed biostratigraphy based on ammonites, inoceramid bivalves, foraminiferans and microcrinoids. The integration of carbon isotope and biostratigraphical data provides a powerful correlation tool, which can be used on a global scale.
