Abstract

The results of comprehensive study of borehole sections drilled on the coastal spits of Taganrog Bay of the Sea of Azov and bottom sediment columns recovered in the water area are presented. A detailed analysis of the former malacological communities, an important participant in the sedimentary process, has made it possible to trace changes in their habitat conditions in the Holocene. Based on determining the absolute age (¹⁴C) from the valves of mollusk shells buried in-situ, it is shown that at the beginning of the Phanagorian regression, in the area of the distal part of Dolgaya spit, there was a sea reservoir with a Sea of Azov–Black Sea complex of index species. By the results of palynological analysis, the changes in the natural conditions of the Azov region over the past nine thousand years are reconstructed and arid and humid climatic phases are identified.

亚速海塔甘罗格湾软体动物、花粉组合和沉积条件分析

摘要

介绍了在亚速海塔甘罗格湾沿岸沙嘴钻探的钻孔剖面和在该水域回收的底部沉积物柱的综合研究结果。对沉积过程的重要参与者——前软体动物群落的详细分析，使得追踪全新世栖息地条件的变化成为可能。通过对原位埋藏的软体动物贝壳瓣膜的绝对年龄（¹⁴ ℃）测定，表明在法纳戈里回归初期，多尔加亚沙嘴远端地区曾存在一个海水库，亚速海-黑海指数物种复合体。通过孢粉学分析的结果，重建了亚速地区九千年来自然条件的变化，并识别了干旱和湿润的气候阶段。
