Added 25 mg/L Silicon (Si) and 5 mg/L Aluminium (Al) to the hydrogeochemical baseline of the Svystunova Gully mine water impoundment, modeling clay mineral phase equilibria using RedModRphree + PHREEQC (Thermoddem database, T = 12°C).
Key thermodynamic outcome (pe–pH diagrams across pH 2–10):
The solid-phase stability field is completely dominated by Beidellite(Na) and acidic forms of montmorillonite (Hmontmorillonite).
