Integrated stratigraphy of the Kronsmoor section (northern Germany), a reference point for the base of the Maastrichtian in the Boreal Realm

Niebuhr, B., hampton, M.J., Gallagher, L.T. and Remin, Z. 2011. Integrated stratigraphy of the Kronsmoor section (northern Germany), a reference point for the base of the Maastrichtian in the Boreal Realm. Acta Geologica Polonica, 61 (2), 193–214. Warszawa. Results of detailed multistratigraphic analyses of the campanian–Maastrichtian boundary section at Kronsmoor in northern Germany are summarised and calibrated with the Gssp at Tercis les Bains, southwest France. Additional markers for the definition of the boundary in the Boreal Realm are proposed, and a detailed carbon isotope curve around the campanian–Maastrichtian boundary in the chalk facies of the Boreal epicontinental sea is presented. The c isotopic Gssp marker for global correlation is the markedly abrupt decrease of c. 0.7 ‰ δ 13
