Изменения климата в Южном Приморье на границе плиоцен-плейстоцена как важнейшего стратиграфического рубежа позднего кайнозоя

The study of diatoms from Southern Primorye's Pliocene deposits permitted to comprehensively reconstruct the climate of the region during the cooling increase at the border of the late Pliocene and Pleistocene. The ecological composition of the diatom flora recorded a trend of rapid decrease of temperatures and water levels in the range of 3.6-2.58 Ma, while the dominant Aulacoseira flora changing to a flora dominated by predominantly benthic taxa (Ellerbeckia, Tetracyclus, Alveolophora) marked a transition from lacustrine to alluvial sedimentogenesis, as well as the evolutionary extinction of ancient representatives of the genus Aulacoseira and their replacement by modern taxa.
