The tectonic condition formed of ore-structures of the Peri-Azovian megablock of the Ukrainian Shield (at the examples fo Dibrovska)
Journal Title: Геофизический журнал - Year 2016, Vol 38, Issue 4
Abstract
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 base¬ment, 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.
