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.

Dynamics of sea level and land on the Black Sea coast during the twentieth and twenty-first centuries
Trends in the sea level and land on the Black Sea coast were explored by using the average annual sea level data on the set of stations in the period from 1874 to 2015. The common regular feature of temporal variability...
Velocity section of the upper mantle under the island arcs of the northern and western outlying parts of the Pacific Ocean
We construct a velocity model of the upper mantle beneath the island arcs in the northern and western parts of the Pacific Ocean for the arrival times of longitudinal seismic waves at seismic stations in these regions. R...
