Abstract

The analysis of diatomaceous deposits in the South of the Russian Far East allowed us to determine the taxonomic composition of the diatom flora and assess its qualitative (ecological) and quantitative traits. The obtained data enabled us to identify biofacies associated with the conditions of diatomite formation and reveal the reasons behind it. Possible reasons of high diatom productivity in the Neogene could be: development of a dense system of rivers and lakes; a long growing season under the conditions of a tropical monsoon climate with mild winters; active volcanic activity, the eruption products of which were the source of materials needed for the formation of valves and supporting the life activity of diatoms.

滨海地区(俄罗斯远东南部)硅藻土形成条件

对俄罗斯远东南部硅藻沉积物的分析使我们能够确定硅藻区系的分类组成，并评估其质量(生态)和数量性状。获得的数据使我们能够识别与硅藻土形成条件相关的生物相，并揭示其背后的原因。新近纪硅藻高产的可能原因是:发育了密集的河流和湖泊系统;在暖冬的热带季风气候条件下的长生长季节;活火山活动，其喷发产物是形成阀门所需物质的来源，支持硅藻的生命活动。

期刊介绍： The algae are heterogeneous assemblage of phytosynthetic organisms, one of the most vast and diverse groups of ancient photoautotrophic pro- and eukaryotic organisms (about 30 000 known species). They are micro- and macroscopic, unicellular, colonial, or multicellular, mobile and immobile, attached and free-living. Algae are widespread in water and soil habitats, at different geographic latitudes, and on all continents. They occur in waters with different degrees of salinity, trophicity, organic matter, and hydrogen ions, and at various temperatures. They include planktonic, periphytonic and benthic organisms. Algae are unique model organisms in evolutionary biology and also are used in various genetic, physiological, biochemical, cytological, and other investigations.
