| 中文摘要: |
| 对国庆矿区开展了1:10000地质简测,在了解矿区地质特征的基础上进行了1:10000土壤地球化学测量工作。Cu、Pb、Zn、Au、Ag 、W、Mo7种微量元素含量特征（变异系数、富集系数和浓集比率）显示,Cu、Au、W元素为区内成矿有利元素。运用统计学软件SPSS19对7种微量元素含量值进行R型聚类分析和R型因子分析,划分出Cu-Pb-Ag和Au-Mo两组主成矿元素组合。采用衬度异常法对成矿有利元素和两组主成矿元素组合进行处理成图,共圈定了2个异常靶区。经过地表工程和深部工程验证,确定了一条一定规模的工业铜矿体。 |

| An 1: 10000 geological survey was carried out in Guoqing mine area, and then an 1: 10000 soil geochemical survey was made on the basis of understanding the geological characteristics of the Guoqing area. Analyses on the content characteristics (coefficient of variation, enrichment coefficient and concentration ratio) of the seven trace elements tested show that the three elements of Cu, Au and W are the ore-forming favorable elements. Furthermore, using statistics software SPSS19, R-type cluster analysis and R-factor analysis, we classified the main mineralization element combinations of Cu-Pb-Ag and Au-Mo. Using the lining value anomaly method, the favorable metallogenic elements and the two main metallogenic elements were processed and mapped, and two abnormal targets were delineated.By surface examination and drilling validations, an industrial copper ore body of a certain scale was determined. |
