Abstract
The Early Cretaceous carbonate carbon isotope stratigraphy established in pelagic limestones is marked by several pronounced excursions towa rds positive delta(13)C values, We investigated a biostratigraphically and palaeomagnetically calibrated Aptian section to see whether C iso tope 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 Barr emian-Albian part of the sequence, were analysed for their O and C iso tope compositions. The C isotope curve established shows two major pos itive excursions which can be correlated with the synchronous and glob ally recognized Aptian C isotope events, The data provide evidence tha t C isotope stratigraphy can be used as a powerful correlation tool be tween pelagic and shallow-water limestone sequences.
