Processes of oxidation and secondary enrichment of sulphide minerals have challenged the minds of geologists, chemists and geochemists for over a century. In spite of extensive and varied investigations in the field and laboratory, the chemical mechanisms involved remain poorly understood. During the past decade, mainly through the pioneering work of Garrels (1960) and co-workers, the concept of thermodynamic mineral equilibria has been applied to reactions occurring in aqueous solutions at surface or near surface conditions. Mineral relationships in the zones of oxidation and supergene enrichment have been graphically portrayed by Garrels (1954) in Eh-pH diagrams by means of thermodynamic calculations following the methods of Pourbaix (1949).
