Figure 2

Morphostructures of the I^st and II^nd ranks, outlined by the MSZ (the III^rd rank elements are omitted in this figure). The thick yellow lines show the lineaments of the I^st rank, and the thinner green lines show the lineaments of the II^nd rank. Solid lines indicate longitudinal lineaments and dashed lines—transverse ones. To describe lineaments in the text, Arabic numerals are used, indicating the points (denoted by black dots) of the intersection of lineaments (defined as nodes).
