Features of mineral composition of rich ores of deep horizons of Vatutinskoye uranium deposit are described. It’s represented by uraninite and brannerite types. Local bodies of rich ores of a deposit are located in secondary structures with stretchings component of the right shear of the Glavnyi Zapadnyi fault. Main structureorganizing line of essentially shear activization PR12 of
Vatutinskoye deposit coincides with direction of the Glavnyi Zapadnyi fault of northwest strike. Bodies alkaline sodium metasomatites are considered as inherited elements of structural paragenesis of the right shear of the main zone of Glavnyi Zapadnyi fault. Component of a stretching of these structures has caused their permeability for ore-bearing fluids, intensive hydrothermal- metasomatic alterations of rocks with formation of local metasomatic bodies and uranium ores.
Key words: alkaline sodium metasomatites, Vatutinskoye uranium deposit.
