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地化特征,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。
elements with electrovalenee change are widely distributed in the nature. Different electrovalence elements have different geochemistry characters, showing different oxidation and reduction environment, and forming typical element combination and mineral association in mineralization process. Using Eh - pH diagram and different geochemical characters of element with electrevalence change, stability of minerals in the nature, and coexisting relation and migration capability of elements with different eleetrevalence are analyzed. Extracting ore - timing information has advantageous to increase achievement quality in the field ore prospecting.
