The object of investigation in this article is the geomorphological space of the Osam-Yantra block step. Closely related to it is the aim of research: elucidation of the morphology and structure and reconstructions of the uniform paleogeographic conditions and processes in the Osam-Yantra block step evolution. The Osam-Yantra structural step is markedly asymmetric, i.e. it has a steep western side and an eastern side, gently sinking east-northeastward. Within the framework of the Osam-Yantra block step, the common regularities and the main stages in the paleogeographic evolution are revealed by means of two basic historical-genetic categories of initial surfaces – conformable and disconformable (or denudation one) to the rock basement and to the corresponding sediments, filling in the earth’s crust depressions. The investigations of these spatial relations facilitate the establishment of the region’s dynamic evolution.
