The tectonic condition formed of ore-structures of the Peri-Azovian megablock of the Ukrainian Shield (at the examples fo Dibrovska)

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.
