摘要
选取巴迪矿区北部异常(Y-1异常)为研究对象,通过对原生晕元素地球化学的化验数据结果,进行R型因子分析和聚类分析处理,并采用最短(邻近)分类准则(nearest neighbor)及皮尔森相关系数,生成聚类分析谱系图,进而探讨各元素间的共生组合关系及空间分布规律,得出巴迪北段异常带异常强度、规模、均匀程度均较低,异常浓度分带不明显,该异常属于非致矿异常.
The authors chose exception （Y- 1 exception） in the North of Badi deposit as the research object, applicated primary halo to carry out the R cluster analysis of the sample data. Using the shortest （near） classification criteria （nearest neighbor） and Pearson correlation coefficient, the authors generated the pedigree chart of cluster analysis, to study the association and spatial distribution between elements. Research results showed that the anomaly with abnormal strength in the North of Badi deposit, size, uniform degree are low, and abnormal concentration zoning is not obvious. So it is concluded that the exception belongs to non mineral anomaly.
