Abstract

Gold mass transfer with chloride and carbonate-chloride solutions was examined at the 300 and 400°C isotherms and P tot = 1 kbar by means of experimental modeling and theoretical simulations. CO2 was confirmed to suppress Au solubility in fluids. The low Au solubility (mAu < 10−8) determined in the experiments explains the mechanism of its precipitation when serpentinites and listwanites interact with acidic mineralized solutions. Listwanitization, which was genetically related with the emplacement of orogenic granitoids, was determined to have overprinted serpentinites and rodingites and strongly affected Au transport in the oregeochemical system. The characteristics of the metasomatic processes in the Ust’-Dep ophiolites and the gold concentration in the rocks produced by these processes confirm this conclusion.
