The Upper Maastrichtian Reference Section of Mt. Klementyev, Southeastern Crimea.

The results of a comprehensive study of an Upper Maastrichtian reference Mt. Klementyev section (Southeastern Crimea), consisting of a terrigenous–carbonate sequence, are presented. It is established that sedimentation occurred in relatively deep-sea conditions. Biostratigraphic analysis of assemblages of benthic and planktonic foraminifers made it possible to recognize the foraminiferal zones in the section and to confirm deep-sea sedimentation during this period.
