Semenenko Institute of Geochemistry, mineralogy and Ore Formation popup.description2 The main results and conclusions of the works are: -within the boundaries of supporting and stratotypical sections of the Dniester-Bug and Bug series it is provided the consistent accumulation of them in Early Archean; on the top of the Pobuzky granulite complex the location of evlizytova formation has been confirmed; within the boundaries of the Sursko GSS in the Middle Prydniprovier the cut of Konka series consists of: Sursko suite, apollonivska thickness, alferivska suite and pashenivska thickness; supracrustal rocks of the plahiogranite-amphibolite SGS are presented by lower metamorphic-ultrametamorphic crystalschist-gneisess and upper metamorphic amfibolite-crystalschist formations; Ukrainian and Baltic shields have a similar development in the Precambrian. The main differences are: the time lack creation of similar formations of Baltic Shield; a large amount of iron-formations in Early proterozoic of US; alkaline magmatism and karbonatite in the time interval of 2740-2623 million years in the Baltic Shield; manifestation of active rifting with formation of basin of Red sea type in the Baltic Shield; special proposition are suggested to improve the existing correlation of chronostratigraphic scheme of Early Precambrian of Ukrainian Shield.
