陕西双王金矿地球化学特征及其成因分析

Geochemical characteristics and genesis of the Shuangwang gold deposit,Shaanxi Province

通过对双王金矿床角砾岩地质特征、地球化学特征的综合分析,认为双王金矿具有不同的矿源深度及剥蚀深度。值得指出的是,Sb、As的变化可作为直接指标,即受剥蚀者Sb表现明显,未受剥蚀者As表现明显;在勘探中Au、Bi、As、Ag、Sb、Mo、Ba、Pb、Zn、Cu、Hg、Mn等可作为双王金矿找矿的指示元素,其中Au、Bi、As、Ag为主成矿元素,Sb、Pb、Zn、Cu为剥蚀深度指示元素,Ba、Hg、Mn、Mo为矿区围岩及地层元素。

Based on an analysis of geological and geochemical characteristics of the Shuangwang gold deposit,this paper holds that there exist different source depths and denudation depths of the gold-bearing breccia. It is worth mentioning that the variation of element Sb indicates denudation,the variation of element As indicates non-denudation,the elements Au,Bi,As,Ag are the main ore-forming elements,Sb,Pb,Zn,Cu indicate the depth of denudation,and Mo,Ba,Hg,Mn contained in surrounding rock can be used in later geological exploration.
