Faculty of the finance and credit popup.description2 The work is devoted to two problems: 1) the structural and compositional regularities in the Early Precambrian structural-formational complexes of the Ukrainian shield; 2) the dependence of the tectonic structures in the plutono-metamorphic associations on the metamorphic conditions. The main results are: 1) it was shown that metamorphic, plutono-metamorphic and plutonic geological bodies in many cases form integral associations, which can be regarded as some "pseudomorphic" rows, where each next member substitutes the previous one. 2) It was shown that cross sections of some metamorphic complexes have symmetrical structures and many plutonic complexes are located symmetrically in space. 3) It was shown that tectonic structure of metamorphic complexes depends not only the depths of forming but also on the ultrametamorphic processes which caused the additional tensions.
