贵州兴仁包谷地背斜金矿地球化学特征及其找矿意义分析

An Analysis on Geochemical Characteristics of Gold Ore and Ore Search Significance in Cornanticline,Xingren County,Guizhou Province

以兴仁包谷地背斜东段金矿体为研究对象,研究了金矿体主量、微量、稀土元素组成地球化学特征。应用矿床预测的相似类比理论,将其成矿地球化学信息与典型矿床——水银洞金矿床进行类比。结果表明,两者成矿地球化学信息具有高度的相似性,但低含量的Au、高含量Sb、强硅化蚀变可能成为研究区内金矿体规模相对不利条件。

This paper studies the gold ore body in the eastern section of comanticline region to explore the geochemical characteristics of the main elements, including the microelements and rare earth elements on the ore （mineralization） spot. Using the predicted theory of similarity analogy of the deposit, this paper compares the geochemical information of its mineralization with that of the typical deposit-gold deposit in Shuiyindong. The result shows that the geochemical infomlation of their mineralization is much similar. Au with low content, Sb with high content and strongly silicified alteration may become relatively unfavorable conditions for the scale of the gold ore body in the research area.
