The results of fluid inclusion studies based on detailed mineralogical investigations
allowed to conclude that mineralization of uranium ore stage began to precipitate in the
temperature range of 500-530oC. At the temperature about 400oC the state of fluids was close to
critical. Deposition of primary brannerite-pitchblende ores occurred at the temperature decrease
down to 350-300oC from Na-(HCO3)-Cl water fluids. Redeposition of primary ores occurred in
the temperature range of 390-160oC and was not essentually separated in time from ore
deposition. Carbon dioxide and bicarbonate-ion were not significant in ore formation.
Presumably, ore forming fluids had magmatic origin, uranium was transported as fluoride (or
chloride) U4+ complexes, and uranium precipitated at the temperature barrier.
