The Central Ukraine Uranium Province confines the Vatuntinskoe, Novokonstantinovskoe, Partizanskoe and Aprelskoe ore fields. All features mentioned above can be divided, based on geological features of each, into such types: VatutinskoNovokonstantinovskiy and Partizansko-Aprelskiy. For the first type mentioned the chlorite-epidote and rybekite-egirine albitites, which form ribbon-like layers, are specific. The second one occurs along linear faults. Ore bodies associated with albitites follow direction of the linear structures. They had simple morphology, flattened and lens-shaped ones. The composition of albitites and type of structural ore precipitation conditions of the Vatutinka, Dokuchaevskoe deposit and the bottom layer of the Novokonstantinovka deposit are similar. On deep horizons of the Novokonstantinovka deposit a bottom ore floor (layer) has been discovered. It is related to a column-like body (layer) of albitites of aegirine-carbonate-biotite composition. The structural ore precipitation conditions in the case are not related to linear seams of mylonites and cataclisites, but zones of pre-ore volume cataclasis. The ore bodies related to them have irregular complex shape. Ore fields of the second type have similar peculiarities.
Key words: Central Ukraine Uranium Province, uranium, alkaline sodium metasomatism, albitite, ore bodies, andradite.
