N2 - Problems of geomorphological mapping Russian seas are discussed. It is based on the principle of analytical mapping which provides the analysis of morphological characteristics of relief and reflection in them of features and conditions of the forming of relief. Stages of development of northern and Far Eastern shelf of Eurasia are revealed: the relief of the first one was formed as a result of recent submersions and risings, deep and transition of sediments during epochs of regressions and accumulative - abrasional smoothing during epochs of transgressions. Analytical approach to geomorphological mapping of seas implies the study of relief morphology as a result of its origin conditions. Relief development stages are recognized for north and Far East shelfs of Eurasia. The relief in the former resulted from recent submersions and risings, sediment destruction and transit during regressions and accumulative-abrasion levelling during transgressions. The relief of Far East shelf of Eurasia was mainly created by Late Alpian faulting movements: in Late Pliocene marine basins began expanding due to abrasion of foothills and inter-mountain plains, deep water hollows formed and widened.
