Determination of the depth of post-ore erosional cut-off in the area of the central anticlinorium of the Yenisei Ridge

Abstract

A summit level of the surface plane is restored according to the watersheds (of the third and a higher order), lying at the plane of the surface, where weathering crust and bauxite-bearing deposits are known. Then the present-day relief is graphically subtracted from the summit surface. The system of contour lines thus obtained reflects the thickness of the layer, removed during the destruction of the initial surface and the depth of post-ore (Pliocene-Quaternary) erosional cut-off.
