Energy Parameters of Ore-Forming Deep Fluid Systems

The energy parameters of ore-forming deep fluid systems (enthalpy and Gibbs free energy) for compounds of S, Cl, and B have been estimated by thermodynamic methods at a lithosphere depth of 1000–20 km. At a depth of 1000 km, ore-forming fluids are dominated by BF3. With a decrease in a depth to 100–20 km, the range of fluid ore-forming systems becomes wider due to the B, F, Cl, and S compounds providing a real basis for development of the voluminous ore-forming fluid systems at the top of the lithosphere.
