摘要：
The Manzurka Alluvium fills ancient valleys of the Baikal-Lena watershed. Previously, the sequence of the constrative alluvium was considered to be of the Eopleistocene age. Latest investigations showed that despite the lithological uniformity, the sequence includes several stratigraphic units ranging in age from the Pliocene to late Pleistocene. The Manzurka Alluvium is a typical example of the polychronous sedimentary complex of the intracontinental frost-free areas that were formed under gradual environmental changes.
