Secular variation in Late Cretaceous carbon isotopes: a new delta C-13 carbonate reference curve for the Cenomanian-Campanian (99.6-70.6 Ma)
- Abstract:
-
Carbon stable-isotope variation through the Cenomanian-Santonian stages is characterized using data for 1769 bulk pelagic carbonate samples collected from seven Chalk successions in England. The sections show consistent stratigraphic trends and δ13C values that provide a basis for high-resolution correlation. Positive and negative δ13C excursions and inflection points on the isotope profiles are used to define 72 isotope events. Key markers are provided by positive δ13C excursions of up to +2...
