Southern Yakutia topography evolution during the Cenozoic

Abstract

Data of loose sediments study and structural-geomorphic investigation permit to identify two planation stages (Paleogene and Pliocene-Early Pleistocene) and two stages of active evolution of topography (Miocene - Early Pliocene and Quaternary). The Quaternary stage is subdivided into two cycles of general uplift and valley erosion and two cycles of autonomous evolution of individual morphostructures, when terraces are formed at positive morphostructures and sedimentation takes place in basins.
