The GSSP for the Campanian Stage - the path to selection and ratification
1 : University of Portsmouth
In 2022, the GSSP for the Campanian Stage, taken at the base of magnetochron 33r in the Bottacione Gorge, Gubbio, Umbria, Italy, was ratified by the International Stratigraphy Commission. Additionally, auxiliary sections were selected in the UK, Poland, Austria, Mexico, and Kansas, USA. Together, these provide a framework permitting high-resolution correlation of the base of the Campanian Stage by the use of palaeomagnetics, carbon isotope stratigraphy and various biostratigraphical groups. The talk provides a historical background to the process of selection of the GSSP, problems encountered en route to submitting a proposal, the importance of auxiliary sections, eventual submission and ratification.
