PlanationSuriaces and zones of riftogenesis

Abstract

A concept of synriftogenic origin of planation surfaces is introduced. In the authors opinion the topography downwearing to the base level proceeds under conditions (and within the zones) of active destructive (riftogenic) endo- and exogenous geomorphogenesis, rather than under conditions of relative tectonic stability. The riitogenesis and connected endogenous-exogenous downwearing of the Earth's surface the authors consider to be the main processes which transform orogenic formations into platformian plateplains and plate-seas.
