摘　　要：采用构造叠加晕的方法,对石人嶂钨矿床V14矿脉的地球化学异常进行系统研究,构建构造叠加晕模型。石人嶂钨矿成矿元素背景含量对数频率柱状图呈"双峰"式分布,显示多次热液成矿作用叠加;单一成矿阶段形成的近矿晕元素组合为W、Bi、Pb、Ag、Cu、Mn,前缘晕元素组合为As、Sb,尾晕元素组合为Sn、Co;矿脉原生晕元素轴向分带序列(由深部到浅部)依次为Co→Bi→Ag→Sb→Be→Mn→As→Zn→Cd→W→Mo;根据构建的构造叠加晕模型,结合前、尾晕共存,轴向"逆向"分带以及前缘晕/尾晕参数从浅部到深部的反复变化等特征,推测V14矿脉沿轴向往深部仍有较大延伸并可能存在隐伏矿体。With the method of structural superimposed halo,the geochemical anomaly of V14 vein in Shirenzhang tungsten deposit is studied,and the structural superimposed halo model is constructed.The logarithmic frequency histogram of background content of mineralization elements in Shirenzhang tungsten is shown in the distribution type of ＂double peak＂,and the superposition of hydrothermal mineralization.The combinations of ore halo elements in a single ore forming stage are W,Bi,Pb,Ag,Cu,Mn.The combinations of leading edge halo elements are As,Sb,and the tail halo elements are Sn、Co.The axial zoning sequence（from deep to shallow） elements of primary halo vein are Co-Bi-Ag-Sb-Be-Mn-As-Zn-Cd-W-Mo in turns.According to the constructed structural superimposed halo model,and the coexistence of the front halo and the tail halo,axial＂reverse＂zoning,and the repeated change characteristics of the parameters from shallow to deep in the front halo,the conclusion can be found that in the deep of V14 vein in Shirenzhang tungsten deposit large extension exists along the axial direction and hidden ore bodies probably.
