| Summary: | Title screen The first results obtained by the numerical physicochemical modeling of uranium and thorium behavior in the radon-rich waters of southern Siberia are presented. The studied waters are characterized by a wide variation of geochemical parameters (pH varies from 5.9 to 10.1; Eh from − 500 to + 285 mV), have diverse chemical composition, with dominating HCO3 Mg–Ca, HCO3 Na–Ca and Cl–SO4 –HCO3 Na, SO4–HCO3 Na–Mg–Ca types, with TDS value varying from 0.2 to 2.6 g/dm3 and silicon content 0.52–32.90 mg/dm3. The possibility for uranium minerals to be formed from the radioactive waters of southern Siberia has been established: In particular, uraninite and thorianite can be most actively precipitated within rather broad range of redox conditions, while uranium black is to occur less frequently. The possibility for thorium minerals to occur in trace amounts is also determined, with thorianite ThO2 as the most probable one. At pH values around 5, the formation of thorium sulfate Th(SO4)2 is also possible. In an acidic, strongly reducing environment with Eh < − 300 mV, trace amounts of ThS2 and Th2S3 may be deposited AM_Agreement |
