| 摘 要： | 红石金矿床是新疆东天山康古尔塔格金矿带中的代表性矿床之一。通过对其地表、已开采中段及部分钻孔的岩石系统采样分析和计算统计,研究了各指示元素在不同位置的组合特征。结果表明:指示元素中Au、Ag密切相关,其他元素组合复杂多变,反映了成矿成晕的多期性、多阶段特点。结合实际勘查资料,采用多种计算方法,建立了矿床原生晕轴向分带模式,即矿床轴向分带(自上而下)为Bi-Mo-Hg-Zn-Pb-Ag-As-Cu-Sb-Au。利用不同中段的7个分带评价值指标确定了矿体的叠加模型。

| Abstract: | Hongshi gold deposit is one of the typical deposits of Kanggurtag gold belt in eastern Tianshan of Xinjiang.Through the sampling analysis and computational statistics of surface,middle part of mining and partial drilling rocks in Hongshi gold deposit,the authors studied the association characteristics of the indicator elements in different positions.The results revealed that element Au is closely related to Ag,and the others are complex and varied,which illuminated the characteristics of multi-phases mineralization.Combining with practical investigation data,the primary halo zoning sequence has been recognized by several calculating methods,which is Bi-Mo-Hg-Zn-Pb-Ag-As-Cu-Sb-Au.Superimposed model is determined,used evaluation index of seven zonations in different middle parts. |
