Biotite oxidation: an experimental and thermodynamic approach
It is generally believed that oxidation of ferruginous biotites proceeds by the oxybiotite substitution: Fe²⁺ + OH = Fe³⁺ + 0²⁻ + ½H₂ The role of this mechanism as an equilibrium process in hydrothermal systems was studied for two compositions, annite, KFe₃,AISi₃O₁₀(OH)₂, and siderophyllite, KFe₂․...
