Аннотация:The study of the foraminiferal communities from the Paleogene–Neogene reference section at
Kvachina Bay in West Kamchatka has made it possible, based on the qualitative composition and the quantitative
ratios of the encountered species, to identify 13 layers with foraminifera corresponding to certain intervals
of the section and to establish their successive change. The foraminiferal layers are combined into four
complex zones. In terms of the distribution scale, the identified zones are regional and are traced in the adjacent
regions. The change in the paleocommunities corresponds to the process of evolutionary development
of foraminifera, as well as to a change in paleoenvironments. The changes recorded in the composition and
the structure of zonal communities are reflected in the stage character of microfauna development.
