Abstract
Indicates that the rhythmic sedimentation pattern is related to changes in surface water productivity. Relative to the marls, the limestone units are typically marked by higher abundances of the planktonic foraminifera G. bulloides, higher numbers of benthic foraminifera, higher δ13C values and lower δ18C values. These characteristics are interpreted as indicating that cool, highly productive conditions existed during the deposition of the limestone units. -File in questo prodotto:
