Abstract
Petrophysical, geochemical, and mineralogical studies of the rocks from the Litsevsky and Priozerny uranium ore sites in the Litsevsky ore district of the Kola region were carried out. The results showed that the density and elastic anisotropy of rocks reflect the intensity of mineralization. High density (3.39 g/cm3) with low values of elastic anisotropy (2.3 %) were noted in rock samples with uranium and sulphide mineralization. Electron microscopy of uranium and thorium phases in the rocks of the Litsevsky ore sites confirmed two stages in the formation of uranium mineralization, separated by the stage of sulphides (pyrite and chalcopyrite) formation. The data obtained can be used in assessing the potential ore content of areas with the manifestation of multi-stage hydrothermal alterations.
