摘要
在五一沟-驼峰山地区,利用元素地球化学参数、变异系数解释图对11种元素进行了数理分析,分析元素的地球化学特征,发现Au、Ag、As、Sb、Mo为主成矿元素。用剩余异常分量因子得分法采用趋势面分析对研究区化探数据进行处理,提取其中反映局部异常变化的剩余异常分量,再对剩余异常分量进行R型因子分析,得到与矿化关系密切的6个因子。用因子得分图描述研究区与矿化密切的地球化学异常分布情况^([1]),通过进一步验证,发现两处金矿化点。
Using geochemical parameter and variation coefficient,the author carried out mathematical analysis of 11 elements as well as element geochemical characteristics in Wuyigou-Tuofengshan area.The author has found that Au,Ag,As,Sb and Mo constitute the major ore-forming elements.The residual anomaly component factor score method which uses the means of trend surface to process geochemical data was adopted in the working area to extract the residual anomaly components that indicate local anomaly changes.R-factor analysis was carried out for residual anomaly components and,as a result,6 factors closely associated with the mineralization were obtained.Score diagrams were drawn to reflect the distribution of geochemical anomalies in the study area.The author discover two gold mineralization bodies by further verification.
