沃溪金锑钨矿床矿化蚀变带地球化学特征

GEOCHEMICAL CHARACTERISTICS OF MINERALIZED ALTERATION ZONE IN WOXI Au-Sb-W DEPOSIT

本文结合矿床地质背景和矿化作用特征。对矿化蚀变带的地球化学规律进行了比较详细的探讨。不同的矿化蚀变作用阶段,矿化蚀变带的常量元素和微量元素、特征元素对的含量比值都是有明显区别的。钨矿化阶段热液富集W、Ca、Mg、Be、Sr、Mo,矿化指示元素为Ca、Mo;金锑矿化阶段热液富集冬Au、Sb、As、Ag、Cd、Be等,矿化指示元素为As、Ag、Cd。为矿床成因及找矿勘探提供了重要依据和重要的标型特征。

Based on the geology and mineralization of the deposit, the geoch-emical characteristics of mineralized-alteration zone has been studied. There are differences in the chemical composition and the content value of mineralized-alteration zone at individual procession. The hydrothermal solution concentrated W, Ca, Mg, Be, Sr and Mo at W mineralization, and path-indicator are Ca and Mo. And Au,Sb,As,Ag,Cd and Be at Au-Sb mineralization, path-indicator are As, Ag and Cd, The suggestion is made for ore genesis and prospection.
