The Earlv Cretaceous carbonate carbon isotope stratigraphy analysed for their 0 and C isotope compositions. The C isotope -. . established in pelagic limestones is marked by several pronounced excursions towards positive S13C values. We investigated a biostratigraphically and palaeornagnetically calibrated Aptian section to see whether C isotope stratigraphy could be recognized in shallow-water carbonates. The chosen carbonate platform sections are located in southern Italy and have been dated by biostratigraphy. Bulk samples, chosen from the Barremian-Albian part of the sequence, were curve established shows two major positive excursions which can be correlated with the synchronous and globally recognized Aptian C isotope events. The data provide evidence that C isotope stratigraphy can be used as a powerful correlation tool between pelagic and shallow-water limestone sequences.
