Integrated microfossil biostratigraphy,Mid-Cretaceous (Albian to Saronian)

Abstract

An attempt is made to integrate biozones based on planktic Foraminifera with those on calcareous nannofossils, mainly on first order correlation. An approximate correlation with ammonite zones, magnetic events and radiometric age values, partly on first-order data, partly from the literature, is added.
