| 摘 要： | 在成矿作用地球化学与勘查地球化学分析的基础上,选取W、Sn、Mo、B i、Cu、Pb、Zn、Au、Ag、As、Sb、Hg共十二种元素作为南岭地区钨矿勘查的重要指示元素。对这十二种指标元素采用等权平均归一化,相关系数加权累加归一化和异常能归一化三种方法进行处理,都可较好地反映该区钨元素的矿化信息,且均比钨元素单指标异常信息效果显著。相关系数加权累加归一化指标主要反映钨元素信息,而等权平均归一化指标和异常能归一化指标主要反映成矿元素的共同矿化信息,这二者在南岭地区对钨矿成矿信息都具有较好的指示作用。

| Abstract: | On the research of mineralization geochemistry and regional geochemical survey in Nanling district,12 elements,W,Sn,Mo,Bi,Cu,Pb,Zn,Au,Ag,As,Sb and Hg,were selected from the regional geochemical survey elements as meaningful indices for tungsten deposits geochemical survey.The 12 indices were integrated as a single index to indicated tungsten mineralization information using three methods as equal weight average,correlation coefficient weighted sum and energy of anomaly.In Nanling district,the three integrated indices all can indicate the tungsten deposits information properly and are all better than the tungsten element single index.The index of correlation coefficient weighted sum mainly indicated the tungsten thematic information while the indices of equal weight average and energy of anomaly mainly indicated the comprehensive mineralization information of the 12 elements.The latter two indices can also reflect the tungsten mineralization significantly in Nanling district. |
