Reconstruction of the composition of the Upper Hadean and Eoarchean crust based on geochemical and Lu-Hf isotopic data of relict and clastogenic zircon of this age. To carry out an age correlation of the oldest crust of the Azov domain with the studied of Hadean-Eoarchean complexes of Canada, Greenland and Western Australia. To perform a petrological and mineralogical study of the BIF of the Western Azov series of the Partizan-Stulnevo anticline. To determine the spatial distribution of 3.3-billion-year-old tonalites that probably made up the Upper Paleoarchean protocraton. To carry out a geochronological and petrological study of garnet-biotite gneisses, BIF and amphibolites of the Tomakivka stratum of the Auly series of the Middle Dnieper megablock in order to determine their age and genesis. To reconstruct the geodynamik conditions of formation of Mesoarchean greenstone structures of the Azov and Middle Dnieper megablocks. Correlation of the magmatic complexes of the Azov and Middle Dnieper megablocks with the KMA megablock. Conduct geochronological and petrological studies of metabasites, metakomatiites and granitoids in the Gaichur structure in order to determine the genesis of this structure. Find Neoarchean (2620 Ma) granitoids in the Pravoberezhny district. On the KMA megablock, granitoids of this age (Ataman complex) and acidic metavolcanites of the Lebedin series complete the Neoarchean section. Compare the Neoarchean-Paleoproterozoic sedimentary-volcanogenic series and magmatic complexes of the Azov and Middle Dnieper megablocks with similar formations of the Pilbara, Kaapvaal, and KMA blocks, which are assumed to have been part of the Vaalbara supercontinent. popup.description2 Research report: 200 p., 61 fig., 25 tables, 164 references.

The object of the study is sedimentary-volcanogenic and intrusive rocks of Archean and Proterozoic age of the Middle-Dnepr and Azov megablocks of the Ukrainian Shield. Based on U-Pb geochronological data, the main stages of crust formation of the Azov and Middle-Dnepr megablocks of the Ukrainian Shield from the Upper Reptilian to the Paleoproterozoic (3.97-2.0 billion years ago) were determined. The composition of the Upper Hadean and Eoarchean crusts was reconstructed using geochemical and Lu-Hf isotopic data of relict and clastogenic zircons of this age. These results indicate a much longer history of crust formation in the Western Azov Sea than previously thought, which increases the prospects for mineral exploration in this area. Economic significance: The results of the work have provided new geological data that will fundamentally change the views on the history of continental lithosphere formation in the Azov and Middle Dnieper megablocks, which will increase the prospects for mineral exploration in this area.
