渣滓溪锑(钨)矿床深部金矿化的发现及其找矿潜力初探
|
摘要
为了探索老矿山渣滓溪锑(钨)矿床深部找矿潜力,在总结对比雪峰山地区的金锑矿化的垂向分带规律的基础上,系统采集矿区深部钻孔岩心及不同标高坑道主要锑矿脉样品分析金,发现这些矿脉在深部普遍有金矿化,往深部随着硅化增强,黄铁矿、毒砂增多,金矿化有增强趋势,且越靠近北西向控矿构造F_3的矿脉金矿化越好。初步认为,金矿化与北西向控矿构造F_3和深部岩性组合的变化关系密切,往深部蚀变矿化增强,推测渣滓溪锑(钨)矿床深部具有良好的找金潜力。
To explore the deep prospecting potential of the antimony(tungsten) deposit of the dregs of the old mine on the basis of the comparison of the vertical zoning law of the gold and antimony mineralization in the Xuefeng mountain area, we collected the samples of the main antimony veins in different elevation tunnels. It is found that the ore veins are generally gold mineralization in the deep. With the increasing silicification, pyrite and arsenopyrite in depth, the gold mineralization is enhanced. The closer to the northwestward ore-controlling structure F3, the better the gold mineralization of the veins is. The results show that the relationship between gold mineralization and NW ore controlling structure F3 and deep lithologic assemblage is closely related. It is predicted that the deep part of the Zhazixi Sb(W) Deposit antimony(tungsten) deposit has good gold prospecting potential.
