The dominant oxidation state of rhenium in high-temperature, chloride-bearing hydrothermal solutions at geologically reasonable oxygen fugacities has been experimentally determined to be +4, although a small percentage of ...

To investigate the aqueous species important for transport of rhenium under subcritical conditions, we conducted a series of solubility experiments from 100 degrees to 200 degreesC at vapor saturation pressures. In these ...
