Abstract:The problems of zonal stratigraphy of the early 21st century are discussed. The great advances achieved in recent years in using zones in geological practice are noted. At the same time, attention is drawn to the controversies existing in the interpretation of the concepts “biostratigraphic zone” and “chronozone,” in the methods of drawing the boundaries of such zones, and in the assessment of the spatial scale of zones and in the understanding of them as stratigraphic units.
