| 摘 要： | K9矿脉是龙门店银矿床主要矿脉之一,为探求其深部资源,应用构造原生晕法进行了深部预测。研究表明:成矿过程具有多期次叠加的特点,840 m标高矿体出现前缘晕指示元素叠加;矿脉自上而下构造原生晕轴向分带序列为W-Au-As-Pb-Hg-Mo-Zn-Bi-Ag-Sb-Cu,出现"前尾晕共存"和"反向分带"现象。依据矿脉构造原生晕特征,建立了K9矿脉构造原生晕叠加模型,并预测840 m标高以下存在盲矿体,具有较大的找矿潜力。

| Abstract: | The K9 vein is one of the main veins of the Longmendian Silver Deposit. The structural primary halo method is applied to make deep ore body prediction. The result shows that the ore-forming process has the characteristics of multi-stage superposition,and the ore body on 840 m elevation exhibits an superposition of frontal halo indicator elements;Axial zoning sequence of the indicator elements downwards on the ore veins by calculation is described as follows: W-Au-As-Pb-Hg-Mo-Zn-Bi-Ag-Sb-Cu,assuming frontal halo and tail halo coexisting phenomena and reverse zoning characteristics. According to the structural primary halo characteristics of K9 ore vein,the ore vein structural primary halo model is constructed and it is predicted that below the 840 m elevation there are blind ore bodies and great prospecting potentials. |
