According to previous studies, the structural pattern of the eastern part of the Ukrainian shield, which was formed during several stages of essentially landslide transformations of crystalline basement, corresponds to dislocation system of displacement-rotation, formation of which took place in Paleoproterozoic. Linear components of the system have got features of formation under geologi- cally-dynamic displacement-pressure conditions; the arched ones - under displacement-rotation conditions. It has been grounded that Dibrovska ore-bearing structure and other similar ones were generated synchronously with the mentioned components of the Peri-Azovian dislocation system. It has been shown that the history of formation of ore minerals, aggregates and bodies is the same as of rock-forming minerals aggregates and ore-bearing bodies. Confinement of ore bodies to pushed forward shadows of pressure in Proterozoic structural pattern is the key search characteristic.

Key words: dislocation system, structures, ore bodies, structural cells.
