Abstract

Охарактеризованы комплексы моллюсков из отложений среднего и верхнего неоплейстоцена местонахождения Восток (Нижнее Поволжье). На основе литологических особенностей осадков и комплексов моллюсков по разрезу прослежено изменение палеоэкологических условий от озерно-лагунных (ранний хазар, сингиль), морских (поздний хазар), аллювиальных (поздний хазар) к морским (ранняя хвалынь).
 The malacological characteristic of the Middle and Upper Neopleistocene deposits of the Vostok locality (Lower Volga Region) is given in the paper. On the base of lithological and textural features of the sediments, as well as mollusc complexes, it is shown that the palaeoenvironment changed from lacustrine-lagoon (Early Khazar, Singil), marine (Late Khazar), fluvial (Late Khazar) to marine (Early Khvalyn) conditions.
