Abstract : A mass-area transposition of fragmentary materials, which plays a determining role in the formation of relief, takes place in the humid climatic conditions of the south of the Far East with its very cold winters causing retention of a continuous frozen state and a deep seasonal frost line in vast areas. In the areas of a lengthy, relatively stable position of the erosion network where a round incision still has not penetrated, the relief undergoes downward development. Destruction of the elevations that acquired a convexo-concave profile occurs by way of lowering the crests and 'under-cutting' the sides of them by means of the gently-inclined surfaces developing on the base while the middle parts of the slopes retain their steepness. When there is an upheaval of the surface (a rising development or even a compensating one), the horizontal surfaces of the terraces encompassed by the slopes are transformed. (Author)
