| 摘 要： | 从区域地质背景和矿区地质特征入手,重点分析了刘家坡地区的土壤金异常晕,表明该区土壤晕分布与构造展布方向一致,金异常晕对地层的选择性不明显.通过对化探土壤测量中Au,Ag,Hg,As,Sb,Pb,Zn,Bi8种元素指标进行R型聚类分析和相关性分析,得出Hg和Sb的相关性最好,Au和As关系密切,属同一类指标;Au,AS,Hg,Sb具有一定的相关性;而Pb,Zn与其他元素基本不相关,并具独立性.因此,研究区内可选用Au,Hg,As,Sb4种元素做为代表性指标进行综合分析,指导成矿预测.

| Abstract: | Based on a study of the regional geological settings and geological characteristics of the mining area, the gold anomaly halos in soil were analyzed mainly in Liujiapo region. The results show that the distribution of soil halos is consistent with the spreading direction of the structure, and the selectivity of halos to strata is not obvious. Through the analysis of Rcluster and correlation of eight elements (gold, silver, mercury, arsenic, antimony, lead, zinc, bismuth which were analyzed in geochemical ex... |
