| 中文摘要: |
| 本文通过在湖南国庆矿区开展地电化学方法测量工作，运用元素变异系数对国庆矿区地电提取测量的14种元素进行找矿潜力分析，得出Cu、Bi两种元素成矿潜力较大；通过R型聚类分析、R型因子分析明确了14种元素的组合特征，划分了三个元素组合（即F1组合:Cr-Co-Ni-Zn-As-Mo-Sb-W-Pb，F2组合:Cu-Bi，F3组合:Au-Ag-Hg)。运用直方图解法、累频法、EDA分别计算研究区异常下限，并进行对比，显示累频法处理本区域地电提取数据较为合理。运用单点元素组合衬度累加法在研究区内圈定组合异常，根据异常的套合情况在研究区内圈定了3个找矿远景区，为在研究区内寻找隐伏铜矿提供了线索与依据。 |
| 英文摘要: |
| A geoelectric-geochemical survey has been carried out in the Guoqing mine area, Hunan Province. By using the element variation coefficients, 14 elements were analyzed, which were extracted from geoelectric measurement in the mine area, suggesting Cu and Bi have major potential of mineralization. Cluster and R-type analyses reveal the combination features of the 14 elements, which are divided into 3 groups, i.e., F1: Cr-Co-Ni-Zn-As-Mo-Sb-W-Pb；F2: Cu-Bi；and F3: Au-Ag-Hg. In terms of the histogram solution, accumulated frequency, and EDA methods, the lower limits of element anomalies of the study area were calculated and compared, showing that processing data extracted from geoelectric measurement by the accumulated frequency method is more reasonable. The single-point element composition contrast method was employed to delineate the composite anomalies in the research area, based on which 3 ore prospective areas were determined, providing clues and basis for further searching for concealed copper deposits in the mine area. |
