| 中文摘要: |
| 文章以甘肃礼县那家坝一带为研究区，通过传统统计学方法与C-A法对Au、Ag、Cu、Pb、Zn、As、Sb、Hg、Bi、Mo十种元素进行异常下限求取，圈出单元素异常图，并探讨两种方法对研究区元素异常圈定的应用效果，验证其优缺性；通过元素共生组合关系及单元素异常分布特征，确定了Au、As、Sb、Hg为此次研究的综合异常分析元素，进一步地对Au、Sb两种元素进行了成矿预测，共圈出Ⅰ、Ⅱ、Ⅲ、Ⅳ四个成矿远景区，其中Ⅰ、Ⅱ成矿远景区成矿的可能性较大。 |
| 英文摘要: |
| This paper uses the traditional statistical method and C-A fractal method to obtain lower limit for anomaly of ten elements Au, Ag, Cu, Pb, Zn, As, Sb, Hg, Bi, Mo and draw single element anomly contour of Najiaba area. Application effect of anomlies defined by the two methods are discussed and their defect and merit identified. According to the element association and single element anomly distribution Au、As、Sb、Hg are determined as the elements for integrated anomly analysis and metallogenic prediction of Au and Sb is made and four potential targets of Ⅰ、Ⅱ、Ⅲ、Ⅳ lineated and target Ⅰ、Ⅱ may be possibly ore-caused. |
