| 摘 要： | 自然界中的变价元素广泛存在,不同价态的元素具有不同的地球化学性状,反映了不同的氧化还原环境,在成矿过程中形成各具特征的元素组合和矿物组合。利用Eh-pH图解和部分变价元素不同价态的地球化学特征,分析自然界中矿物的稳定性和不同价态元素的共存关系及迁移能力,从中提炼找矿信息,有利于提高野外找矿评价工作成果质量。

| Abstract: | Valence-varying elements are extensively existent in nature.Elements of different valence states have different geochemical behaviors,which reflect different redox environments.In the ore-forming process,these elements can form their respective characteristic element associations and mineral assemblages.Using Eh-pH graph and geochemical characteristics of some valence-varying elements with different valence states,the authors analyzed mineral stability and coexistence and migration capacity of elements with different valence states so as to extract ore-prospecting information and thus improve the quality of evaluation of ore-prospecting work. |
