Resumo
Complex geological and paleobotanic analysis of sections of the boundary Oligocene–Miocene sediments of southern Primorye is conducted. The presence of a stratigraphic hiatus is identified in the transitional complexes of the Pushkino and Pavlovka depressions but not in the sections of the Rakovka depression; thus, it is suggested to use one of them (borehole no. 15) to choose the stratotype of the Paleogene–Neogene boundary. The previous conclusion on the presence of economic coal deposits of Primorye within the Paleogene part of the Tertiary complex is supported. It is suggested to use the section which is exposed by the Rakovka brown coal open pit (point 9209) as a stratotype of the upper subformation of the Pavlovka Formation.
