“…It should be noted that in terms of the total con tent of lanthanides, the fluorites from finegrai ned graypink Ruska Polyana granites (∑REE = = 26933 g/t) is comparable to the fluorites from the Perzhanskyi granite (∑REE = 23390 g/t) [11]. The Perga fluorite differs from the Ruska Poly ana fluorites (Fig.…”

Introduction. To date, rare earth elements (REE) are used to manufacture most high-tech goods and are crucial in defense technologies (lasers, radars, and electromagnetic weapons), nuclear engineering, metallurgy, and others. All this determines the relevance of their study to assess the rare earth mineral resource base of Ukraine. Problem Statement. The determination of REE in rocks and minerals is a fundamental problem in geochemistry and petrology for understanding the processes of rock formation. However, it is a complex analytical task related to the similar chemical properties of these elements, which are caused by the "lanthanide compression effect". Purpose. The purpose is to develop analytical technologies for determining REE content by the ICP-MS method, to evaluate their content and distribution in granitoids of the Ukrainian Shield. Materials and Methods. The hybrid method of ICP-MS analysis and microwave decomposition of rocks and minerals has been used to measure the REE content. This technique has been tested and used to estimate the content and distribution of REE in fluorites and rare-metal granitoids of the Rusko-Polyanskyi massif of the Korsun-Novomirgorod pluton of the Ukrainian Shield. Results. Analytical technologies for determination of REE in granites and minerals have been developed. The method for determining REE in fluorites and granites without their prior concentration in the range from 0.01 to 1000 ppm with a relative standard deviation of 0.01–0.10 has been described. The content of rare earth elements in the Rusko-Polianskyi granites increases (218–797 g/t), the main concentrator of these elements is fluorite (692–26933 g/t REE). An inverse relationship has been observed between the REE content in fluorites and granites. Conclusions. The developed analytical technologies are the basis for establishing quality assessment criteria and developing principles for the rational use of rare-earth granitoids to create a rare-earth mineral resource base in Ukraine.

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.

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.
