Carbon-isotope stratigraphy of Cenomanian-Turonian platform carbonates from the southern Apennines (Italy): a chemostratigraphic approach to the problem of correlation between shallow-water and deep-water successions
|
Abstract:
The carbon-isotope record of three sections of shallow-water carbonates from the Upper Cretaceous sequences of the southern Apennines (Italy) shows a pronounced positive excursion of about 4-5[per thousand]. Using the upper Cenomanian Cisalveolina fraasi level as a biostratigraph
ic tie-point we correlate this excursion to the OAE-2 isotopic event. Comparison with the standard reference δ^sup 13^C curve of Eastbourne (England) shows that the overall character of the excursion is clearly reproduced in the shallow-water curves. Chemostratigraphic correlation allows definition of ...
