Kuryakova, G.A., and Florinsky, I.V., 1991. Analysis of Spatial Relationships between Ring Structures, Topography, and Soil Cover. Pushchino Research Centre Press, Pushchino, 14 p. (in Russian, with English abstract).

 

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.
