【摘要】 通过对青海大柴旦镇长征沟多金属矿1:25000地球化学沟系岩屑测量,对2394件化探样品进行Au、Co、Ni、Cu、Zn、Pb、As、Sb共8种元素分析测试。基于SPSS软件平台,对样品分析结果通过多元统计学中的聚类分析及因子分析进行元素组合规律研究。聚类分析结果显示:As-Sb-Pb、Co-Ni-Cu-Zn、Au各为一类,相关性好;因子分析结果显示第一成分F1代表了Co-Ni-Cu-Zn元素组合,第二成分F2代表了As-Sb-Pb元素组合,第三成分F3代表了Au元素组合。聚类分析与因子分析结果很好地吻合,结合区域元素组合规律,得出As-Sb-Pb相关性高,往往为矿化剂,Co-Ni-Cu-Zn、Au为成矿元素,元素组合分布规律研究为进一步找矿方向提供依据。更多还原

【Abstract】 A total of 8 elements of Au, Co, Ni, Cu, Zn, Pb, As and Sb were detected in 2394 geochemical samples by measuring the 1:25000 geochemical channel debris in Changzhenggou polymetallic deposit, Dachaidan Town, Qinghai Province. analysis test. Based on the SPSS software platform, the sample analysis results were studied by cluster analysis and factor analysis in multivariate statistics. The results of cluster analysis showed that As-Sb-Pb, Co-Ni-Cu-Zn and Au were each one, and the correlation was good. The factor analysis showed that the first component F1 represented the Co-Ni-Cu-Zn element combination. The two component F2 represents the As-Sb-Pb element combination, and the third component F3 represents the Au element combination. The results of cluster analysis and factor analysis are in good agreement. Combined with the combination of regional elements, it is concluded that As-Sb-Pb has high correlation, often mineralizer, Co-Ni-Cu-Zn and Au are mineralization elements. The study of combined distribution law provides a basis for further prospecting.更多还原
