To the problem of formation of Neopleistocene water structural and formational complex of Ust-Selenginskaya hollow (east coast of Baikal lake)

On the basis of paleohydrological, lithological-stratigraphic and facial analyses of water genesis deposits the conditions of sediment accumulation by neopleistocene terrace complex of Ust-Selenginskaya hollow are reconstructed. The environment of accumulation of lake and lake-river sands of high terraces of this hollow were shallow limnologic reservoirs. Regular changes of a water level in Baikal, their ingression in Selenga River valley (three stages) were a consequence of the differentiated tectonic movements in Pribaikalye. Low terraces have a binomial structure and are put by sediments with normal power alluvium.
