We carried out an analysis of relationships between topography, ring structures, soil cover and rocks at a regional scale. The study area was the Ural Region, Russia. We (a) compiled a map of convergence and divergence areas (horizontal curvature is negative and positive, correspondingly), (b) derived a map of ring structures from the map of convergence and divergence areas, and (c) carried out a combined analysis of these two maps and a set of soil and geological data. The following regularities were found. Let there be two ring structures defined by two circles. These circles border two heterogeneous subsets M and N of convergence and divergence areas. Let one circle intersects another. This brings into existence a segment including a subset L of convergence and divergence areas. A design of the subset L differs from designs of the subsets (N–L) and (M–L). Segmentation of the subset M can be observed until a subset K can be separated. This subset has a homogeneous design of convergence and divergence areas. Different groups of subsets K can be merged into extended ‘clusters’ with dominant soil complexes and rocks. Terrain fragmentation into segments and their merging into ‘clusters’ can be considered as a formalised protocol for determination of borders of areas marked by dominant soil complexes and rocks.
