| 摘 要： | 作为地壳中常见的主要变价元素—铁 ,它与金在内生成矿及表生再富集过程中的关系十分密切。铁在矿床中的分布及铁的硫化物矿物在氧化过程中演化的阶段性与环境的Eh值,pH值有着密切关系;进而影响和控制了金在表生演化过程中的地球化学行为。

| Abstract: | Iron,which is one of the common and major changeable valence elements in the crust,is very well interrelated with the gold endogenetic mineralization and supergenetic enrichment.The distribution of iron in a deposit and the evolution of sulphide minerals of iron during oxidation,closely related with the values of Eh and PH of the surrounnding environment,influenced and controlled the geochemical behaviour of gold during supergenetic evolution. |
