Abstract

New data on finds of representative diatom assemblages in the marine Cenozoic section of West Kamchatka (Kvachina Bay) are presented. Planktonic species of stratigraphic importance were found in the assemblages. Analysis of stratigraphic occurrence of various taxa in the section resulted in the identification of a series of biostratigraphic units with the rank of local zones. Correlation of the assemblages with the North Pacific diatom zonation is outlined. The early Oligocene to early Miocene age of the host deposits is concluded.
