Ecological Condition of Diatoms Flora in Holocene Sediments of Razdolnaya River (Far East of Russia)

Abstract:

The ecological structure of diatoms communities was researched from sediments of the First Razdolnaya river terrace (Southern Primorye). The obtained data allowed to establish climatic rhythmics and the related transgression-regression cycles, are typical for the area of researches. The analysis of the replacement lagoon-marine diatoms complexes by lacustrine, alluvial and marsh ones allow us to establish the amplitudes of the Japan Sea fluctuations and ingression penetration into river valley. The maximum of the ingression penetration (up to 23 km from sea-shore) toward river-valley corresponds to Holocene climatic optimum. The sea level could exceed modern on +3m at this time and influenced on the coastline formation.
