Abstract
The features of distribution of uranium of albitites of the Novokostiantynivka and the Partyzanske deposits of the Central Ukraine Uranium Province of the Ukrainian Shield is considered in the paper. Ore layers of the Novokostiantynivka deposit have specific dark-colored minerals: top level — rybekite, aegerine, chlorite, epidote; bottom level — aegerine, biotite, magnetite, andradite. In albitites of the Partyzanske deposit there are wide-spread dark minerals such as rybekite, aegerine, actinolite, diopside, andradite; typical feature of the most of albitite types is a Fe-Ca garnet. No clear relation between uranium and thorium in albitites of the Novokostiantynivka deposit has been detected. It differs from albitites of the Partyzanske deposit, where several albitite types with strong correlation between uranium and thorium are observed: aegerine-andradite “ore” and rybekite-andradite-aegerine.
