Albian high-resolution biostratigraphy and isotope stratigraphy: the Coppa della Nuvola section pelagic succession of the Gargano Promontory (Southern Italy)
High-resolution δ13C and δ180 curves, calibrated against planktonic foraminiferal and calcareous nannofossil biostratigraphy, are provided for the upper Aptian–lower Cenomanian pelagic succession of the Gargano Promontory (Coppa della Nuvola section, southern Italy). The succession consists of two s...
