Abstract

The state of the mineral resource base of uranium and a number of problems in nuclear power approves the necessity to use Thorium as a fuel for nuclear power plants. The paper briefly describes the state of knowledge about thorium in Ukraine, especially its geochemistry and metallogeny. The data on thorium-bearing of Ukrainian shield basement rocks is given. Also is given the history of thorium accumulation in the rocks. The parameters of thorium mineralization in rocks of basic geological formations of the Ukrainian Shield (mean thorium content, mean Th/U ratio, coefficients of variation of thorium and uranium contents) are shown. The places of locations of thorium-bearing and geochemically specialized formations on thorium in crystalline rock, in mega blocks and inter block suture zones of the Ukrainian Shield are described. It is concluded that the main prospects for the creation of the mineral resource base of the metal should be associated with the development of an alkaline intrusive magmatism, metasomatosis and hydrothermal activity in the foundation board of the Shield.

 

Key words: distribution of thorium, crystalline rocks, thorium-bearing, nuclear power, the accumulation period, thorium geochemistry.
