ИСТИНА

The Late Quaternary history of the Caspian Basin remains controversial. One of the major disagreements in this debate concerns the stratigraphic correlation of various deposits in the Caspian Basin. Differences in tectonic regime and in preservation of the geological record in different regions have prevented reliable correlation of local stratotype sections across the region. Because of the absence of a reliable chronology, each region is described in terms of its own self-contained stratigraphy. The Lower Volga region is uniquely attractive for its record of palaeogeographic events, and for the opportunity to build a single stratigraphic and palaeogeographic history of the Pleistocene of Central Eurasia.
