“…Turning to the question of Ore-bearing Sushchany-Perga fault zone it should be noted [Nechaev et al, 2019] that the most number of deposits and ore occurrences of US minerals are associated with fault zones. Faults serve as channels for the entry into the upper layers of the platform covered of hydrogengas fluids and the exhalation of chemical elements in the form of free atoms and ions.…”

“…The Yuriyivsky massif of titanium-bearing gabbroids, Yastrubets massif of syenites (comes from the Korosten pluton [Мitrokhin, 2011;Dubyna, Kryvdik, 2014]), Sushchany disthene deposit, as well as, placers and bed-rocks of the tin (cassiterite), tantalum-niobium ores are situated in the field of Perga granites. Scheelite skarns with superimposed sulfide and precious metal (Ag, Au) mineralization and other minerals are known in the area [Bogdanova et al, 2004;Kondratenko, Kostenko, 2015;Galetsky et al, 2016;Ponomarenko et al, 2017;Nechaev et al, 2019]. Molybdenum mineralization is located within the area of distribution of medium-coarse-grained leukogranites of the Ustynivka ore in the area of propagation [Kondratenko, Kostenko, 2016].…”

The field tectonophysical works were carried out in the upper reaches of the Ubort River basin along the Zolnia-Maidan-Kopischany fault. The research aim was determination of the inner structure and kinematics of the Sushchany-Perga fault zone of the western pfrt of the Ukrainian Shield. For investigation of fracturing and structural-textural elements of rocks the structural-paragenetic method of tectonophysics was used. It was determined that formation of the Sushchany-Perga fault zone continued during at least five phases of deformation. They were accompanied by the formation of differently oriented shear zones: Khmelivka, Sushchany, Perga, Rudnia-Khochin, Lopatychi. The Khmelivka and Sushchany shear zones are similar to striking of the Nemyriv and Khmelnik fault zones of the Ukrainian shield, which belong to the Nemyriv stage of faulting (~1.99 Ga). The Rudnia-Khochin and Perga phases are related to the fact that the Sushchany-Perga fault zone was quite active during the junction of the Fennoscandia and Sarmatia microplates. We have established that the development of thrust fault and normal down throw fault type shears, which took place in an area of compression and extension, respectively, is associated with the formation period of the Perga granitoids complex (1.80—1.70 Ga).This alternation of the compression and extension conditions has led to formation of the ore occurrences and deposits within the Perga tectonic joint. This investigation found that the Sushchany-Perga fault zone arose in the Late Paleoproterozoic at the Nemirov stage of fracture formation, simultaneously with Goryn, Lutsk, Teteriv and Nemyriv fault zones as a result of the junction of two ancient microplates — Fennoscandia and Sarmatia.

“…Анализ особенностей распределения различных месторождений и рудопроявлений в разломно-блоковой тектонике Украинского щита (табл. 1,2) МШЗ хорошо выделяются в геофизических полях, для этих зон характерен очень сложный рельеф поверхности Мохо и утолщение коры по сравнению с сопредельными мегаблоками. На глубинном уровне МШЗ установлены коромантийная смесь и несоответствие между глубинными мантийными блоками и современными границами этих зон, что свидетельствует о горизонтальном аллохтонном перемещении пород этих зон (например, Волчанский выступ Орехово-Павлоградской зоны) [Гинтов, 1978].…”

Введение. Украинский кристаллический щит имеет разломно-блоковое строение, тектоническое районирование которого включает шесть мегаблоков, три межблоковые шовные зоны и региональные глубинные долгоживущие разломы. Подавляющее значение в локализации оруденения имеют именно региональные и локальные зоны разломов [Нечаев и др., 2019а,б], являющиеся наиболее флюидопроводимыми структурами. Геодинамический режим этапов развития мегаструктур,

Scientific review of the latest author’s works on tectonics and geodynamics of the territory of Ukraine, as well as its connection with the localization of mineral deposits, is presented. The structure and evolution of lithosphere of the Carpathian and Black Sea segments of Ukraine, the Dnieper-Donetsk Basin, Donbass Foldbelt and Ukrainian Shield has been reconstructed based on the interpretation of regional deep sounding (DSS) and reflection (CDP) seismic profiles, the geomagnetic field data, geological-structural mapping, paleotectonic, numerical modeling, paleogeographical and palinspastic reconstructions. When interpreting the DSS profiles, the classic velocity models are supplemented with seismic images obtained by the original finite-difference reflection/refraction migration method. The monograph included scientific study carried out at the S.I. Subbotin Institute of Geophysics of the National Academy of Sciences of Ukraine with the involvement of seismic and related geophysical data obtained as a result of conducting and interpreting regional wide-angle seismic profiles (WARR): DOBRE’99, PANCAKE and RomUkrSeis. Geological interpretation of reflection seismic profiles of the Ukrainian sector of the Black Sea, paleogeographical and palinspastic reconstructions contributed to the study of the evolution of the entire Black Sea region. The geological evolution of the Ukrainian Carpathians is reconstructed on the basis of updated data on stratigraphy, tectonics, lithology and sedimentology and palinspastic reconstructions. The structure and development of the DDB sedimentary cover was revealed by seismogeological sections along numerous reflection (CDP) seismic profiles. The tectonics of the Precambrian Ukrainian Shield, including the Kryvyi Rih-Kremenchug and Golovanivsk suture zones, were studed by geomagnetic field analysis and detailed geological and structural mapping.
