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

摘要: 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。

Abstract: 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.
