Abstract

The coast of the shallow Azov Sea is characterized by a series of sand spits. Based on the results of drilling conducted on Dolgaya Spit, which separates the water area of Taganrog Bay from the rest of the Sea of Azov, we consider the structure of the upper part of the geological section of these coastal accumulative forms. Core samples obtained during drilling made it possible to determine the change in thickness of Holocene sand-shell deposits and underlying Middle Pleistocene layers. It is shown that the formation of the spit began more than 5 ka ago during the initial stage of the New Black Sea transgression and occurred as a result of sequential attachment of beach bars to it.

亚速海沉积物研究（以多尔加亚火山口为例）

摘要

浅亚速海的海岸以一系列沙嘴为特征。基于在将塔甘罗格湾的水域与亚速海其余部分分隔开的Dolgaya Spit上进行的钻探结果，我们考虑了这些沿海累积型地质段上部的结构。在钻探过程中获得的岩心样品使得确定全新世沙壳沉积物和下层中更新世层厚度的变化成为可能。结果表明，在新黑海海侵初期，吐气的形成始于5 ka之前，并且是海滩条依次附着的结果。
