Interrelation of planation surfaces belonging to different stages of geomorphic evolution of the Chikoi-Daurian uplift

Abstract

A widespread planation surface reliably dated from Cretaceous. Paleogene is located at watersheds of the Central Transbaikalian periferic ridges. Late Jurassic surface is established at two levels-within depressions and at ridges, their jointing can be traced along the summit surface. Angle discordance is established between the Late Jurassic surface and younger ones. Outer and inner limits of the young surf aces are traced, which predetermined stepped topography of the ridges and reflect the succession of their formation.
