通化集安板房沟地区土壤异常特征与找矿前景

Soil anomaly characteristics and prospecting potential in region of Banfanggou of Ji'an,Tonghua

根据集安板房沟矿区的土壤测量结果、R型聚类分析、相关性矩阵分析、R型因子分析和优选异常进行查证,确定了Au异常带主要沿着老岭群板房沟组的北东向构造展布。老岭群和集安群的土壤聚类分析表明,Au元素在老岭群中呈独立化学行为,在集安群中与As有一定的相关性,Sb、Hg、Bi在老岭群与集安群中均具有较好的相关性。在老岭群和集安群的因子分析中,F1(主要为Zn、Ag、Sb、Pb、Bi、Cu、Hg)代表了多金属的矿化作用,F4(Au)代表了金的成矿作用。区域内的异常主要是沿北东向展布,对其中5个主要的Au异常点进行了详细的查证,发现了一些Au矿化体,预示了良好的找矿前景。

The distribution of gold anomaly zone mainly along the Laoling Group Banfanggou Formation of the North East trending structures is determined according to the measurement results of soil in Banfanggou mining area of Ji＇an, R-type cluster analysis, correlation matrix analysis, R-type factor analysis and investigating the high abnormal value area. Soil cluster analysis of Laoling Group and Ji＇an Group showed that the Au element has not correlation with the eles elements in Laoling Group,but Au element and As element have a certain correlation in the Ji＇an Group and Sb, Hg and Bi have good correlation in Laoling Group and Ji＇an Group. F1（Mainly for Zn, Ag, Sb, Pb, Bi, Cu, Hg） represents a multi metal metallogenesis and F4（Au） represents the gold metallogenesis in factor analysis of Laoling Group and Ji＇an Group.The anomalies in the area are mainly distributed along the north east direction, five maim Au anomalys of them are checked, some Au mineralized bodies were found,predicted a good prospect for ore prospecting.
