metadata.name: dc.description.abstract
metadata.value: This article presents new data from geochronological study the lake-bog organic-rich layer
  from of the “Ilya Prorok” sequence (Upper Volga Basin, Tver Region) that is a one of the reference
  sections located on the Russian Plain. Ideas concerning the age and climatic conditions
  of these organic--mineral deposits formation changed significantly over the long history of
  their study. As a result, the viewpoint about the belonging of this layer to the Likhvin time began to prevail. However, it is still unclear with which marine isotope-oxygen stage (MIS) the
  Likhvin interglacial can be compared. According to the paleobotanical study of the lake-bog
  from the Ilya Prorok section, it was confirmed that the lower part of the lake-bog layer can be
  attributed to the warm phases of the Likhvin interglacial, while its upper half was deposited
  during the transition to cooling after the interglacial period. For the first time, the radioisotope
  age of the buried lake-bog deposits of the reference section “Ilya Prorok” have obtained.
  According to the data of direct 230Th/U dating, the formation of the sequence probably began
  no earlier than ~ 326–260 Kyr ago. The 230Th/U age of the buried peat bog from its upper half,
  according to the results of applying the isochronous approximation, can be correlated with
  the interval ~ 256–225 Kyr ago. According to these data, the Likhvin deposits were formed no
  earlier than MIS-9.
