Abstract
The problems of mapping the relief of deep-sea surfaces are mainly associated with the impossibility of obtaining data on the geological structure of the discovered forms, which often makes it difficult to unambiguously determine their genesis. The paper provides examples of using additional information to increase the reliability of conclusions about the relief of the bottom surface of a deep-sea basin. To clarify the genesis of the bottom forms of the Baikal Basin, published data from seismic and geophysical studies of the bottom surface, and core drilling materials were widely used. As a result of the analysis of the obtained material, the genesis of the remnants on the underwater slope of South Baikal was established, and it was found that the sharp turns of the valleys of some canyons are explained by the lithological, structural and textural features of the slope deposits.
