摘要
通过对惠井子地区进行岩石化探测量,圈定出该地区的铜异常晕,结合研究区地质特征,对铜异常晕特征进行评价分析,研究区铜异常晕分布与构造展布方向一致,铜异常晕对地层的选择性不明显。对岩石化探测量中Au,Ag,Cu,Pb,Zn,Mn,Mo,Sb,Bi的9种元素指标进行了R型聚类分析和相关性分析,其中Cu,Zn,Mn相关性较好,其他元素相关性较弱。因此,在研究区可选用Cu,Zn,Mn等3种元素作为代表性指标进行综合分析,指导成矿预测。
Based on rock geochemical exploration survey in Huijingzi region, it is delineated the copper anomaly halos in the region, and combined with mine geological characteristics to evaluate copper characteristics of anomaly halos. The results show that the distribution of copper anomaly halos is consistent with the spreading direction of the structure in research area, and the selectivity of copper anomaly to strata is not obvious. Through the R-cluster analysis and correlation analysis of nine elements （gold, silver, copper, lead, zinc, manganese, molybdenum, antimony and bismuth）, Cu, Zn, Mn of correlation is better, other elements correlation is very feeble. Therefore, three elements of Cu, Zn, Mn are supposed to be a representative index for comprehensive analysis to guide the exploration in the research area.
