Abstract

The current state of Cenozoic marine diatom biostratigraphy and the principles of construction of oceanic zonations are reviewed. High-resolution oceanic diatom zonations that are widely used for the detailed subdivision, dating, and correlation of Cenozoic sediments of the world’s oceans are also discussed. The successful application of these zonations in studies of sequences on land and in marginal seas is critical to biochronology. Some difficulties and obstacles in the application of zonal subdivisions based on marine diatoms are examined. Among the main existing problems are the following: the use of different types of zone whose boundaries are marked by various datum levels, the geographic constraints of diatom zonations, difficulties in correlation of diatom assemblages across different marine facies, and the presence of a certain amount of diachroneity in the boundaries of biostratigraphic zones.
