Largest landforms of the Russian Plain and their relation to the earthcrust structure

Abstract

The paper presents results of the trend-analysis of the present-day surface topography, pre-Riphaean basement surface and the Mohorovicic discontinuity within the limits of the Russian Plain. Landiforms of different ranks are shown to differ in the interrelation between the surfaces. Mega forms (average radius 500 km) most clearly show an inverse relation of the present-day surface to the basement surface topography, while in macroforms (average radius about 250 km) the basement surface in inversely related to the Moho discontinuity. The author speculates conserning the deep processes character which account for the mentioned relations.
