Abstract
Reported for the first time in this paper are the results of simulating experiments on the rirradiation-induced oxidation of Fe2+ under the physicochemical conditions (T= 200°C,P= 50 MPa,Eh=−0. IV, pH = 7.2) similar to those under which moderate-low temperature hydrothermal uranium deposits are formed. Evdence shows that the effect of groundwater radiolysis seems to be the major mechanism of wall-rock alteration (hematitizaton) of hydrothermal uranium deposits. Moreover, a discussion was made of possible effects of radiolysis of the water-rock system on wall-rock alterations including argillization and decoloration of uranium ore deposits on the basis of the experimental results.
