[en] Data on the ground radiogeochemical sampling of (Pz-Mz) granitoid block in crystal framing of depression are processed, the redistribution of uranium and accompanying elements in the block rocks is assessed and their distribution peculiarities being shown. Contents of Th, U and accompanying elements were determined by X-ray spectrometric and spectrum analysis. The determination of bond stregth of U and Th contents and Th/U value permits to evaluate the intensity of uranium mobilization in rocks of crystal base block. U redistribution is conditioned by the processes of hydrothermal-metasomatic acid leaching. Zones of uranium redistribution in granitoids occupy a greater area, than metasomatite aureoles. Geochemical similarity of granitoids and ore formations of the depressions permits to assume, that granitoids are not only U source, but also the source of accompanying elements (Mo and Pb)
