According to the materials of scientific report at the meeting of the Presidium of NAS of Ukraine March 2, 2016

The stress-strain state of the Earth’s crust of  the North-Western and Central parts of the Ukrainian shield during jointing of Fennoscandia and Sarmatia terranes and the formation of the Korosten and Korsun-Novomirgorod plutons of gabbro-anorthosites and rapakivi is considered. It is shown that the difference defined by fracturing in the orientation of the axes of the main normal stresses in the formation of the Korosten and Korsun-Novomirgorod plutons in the interval of 1.80–1.75 Ga was caused by the fracture formation of the first pluton ahead of the second one at ~10 Ma and Sarmatia’s turning counterclockwise to 54°. Some geodynamic criteria for prospecting for ore minerals are formulated.
Keywords: deformations, fault zone, crack, plutons, ore deposits, rotation plates.
