Abstract

At high PT parameters of cumulates of ultramafic–mafic intrusions and low oxygen fugacity (below QFM buffer), Pt in the form of a carbonyl complex is dissolved in a CO2-bearing fluid. The high solubility of Pt chloride in brines with NaCl, which is related to the formation of low-sulfide deposits of platinum group elements, is attained only at high oxygen fugacity (above the QFM buffer). It is suggested that native platinum at low oxygen fugacity in low-Н2О СО–СО2 (Н2О) fluid can also transit into a cation-soluble form due to the reaction of chloration. The experimental data are provided for the interaction of NaCl with magnetite and chromite (accessory minerals of ultramafic–mafic intrusions) at Р = 200 MPa, Т = 950°С, and fO2 <QFM with the formation of Fe and Cr chlorides. As shown by thermodynamic calculations, the FeCl3 and FeCl2 equilibrium provides a high chlorine fugacity (fCl2), which is only 3–4 orders of magnitude lower than fCl2 in Pt–PtCl2 equilibrium and 2.5–3.0 orders of magnitude higher than in 1 M HCl aqueous fluid at the same Р‒Т–fO2 parameters.
