Lake sediments correlation of South and Middle Ural lakes

The сorrelation of lake Itcul (Middle Ural), lake Ufimskoe, lake Siritcul (South Ural) Holocene sediment profiles was carried out. The studied territory was established to be characterized by the following Holocene events: the Preboreal oscilation, the Boreal second half cooling and aridization, the Atlantic end climatic optimum, cooling and aridization early in the Subboreal and in the mid-Subatlantic. The possibility of geochemical, lithological, pollen, and diatom correlation of even-aged cores was noted.
