谢永贵地区土壤化探因子得分异常靶区圈定

The Application of Soil Geochemical Anomaly Component Factor Score to Delineation of Prospecting Targets in the Xieyonggui Area

用R型因子分析方法对阿荣旗谢永贵地区1:1万土壤化探数据进行了分析表明,10种微量元素可以分为Cu、Ag、Au、As、Mo;Pb、Zn、Bi、Hg及Sb三类。第一类是反映了中低温的矿化元素组合,第二类反映了中温的指示元素组合。该地区采用因子得分趋势面分析,对剩余异常进行累加法分析成图,共圈定了Ⅰ、Ⅱ、Ⅲ、Ⅳ四个异常。石英脉或蚀变岩型Au矿是异常区内的主要找矿重点地段。

This work uses the R-type factor analysis for analyzing the date of 1：10000 soil geochemical survey in the Xieyonggui area. Factor analysis on the soil geochemical data of the Xieyonggui area shows that trace elements here can be divided into three groups, i.e. Cu-Ag-Au-As-Mo, Pb-Zn-Bi-Hg, and Sb. The first group is element association of low-temperature mineralization, the second group is element association of medium temperature mineralization. This paper uses trend surface analysis of factor score to delineating 4 anomalies I, II, III and IV in the Xieyonggui area.
