内蒙古沙锡拉特地区土壤地球化学特征及找矿方向
|
摘要
内蒙古沙锡拉特地区位于大兴安岭多金属成矿带中段,为明确找矿方向,对研究区进行1∶1万土壤地球化学测量。采用单元素异常、组合异常与因子分析对研究区土壤地球化学数据进行评价。单元素异常显示,Ag、Pb、Zn与Sn元素的异常规模大、强度高。组合异常圈定4个异常,分为Ag—Au—As—Sb与Bi—W—Pb—Zn—Sn两类。因子分析将所分析元素分为五组,其中F1因子由Ag—Au—As—Sb元素组成,F2因子由Pb—Zn—Sn元素组成。根据土壤地球化学异常特征与区域成矿地质条件,在本区圈定2个找矿靶区,BQ—1为Pb—Zn—Sn找矿靶区,BQ—2为Ag找矿靶区。
Shaxilate area is located in the middle segment of the metallogenic belt of Da Hinggan Mountain.In order to provide ore-prospecting direction,the 1:10 000 soil geochemistry survey in the study area has been undertaken. Single element anomaly,composite anomaly and factor analysis are used to evaluate the soil geochemical data. The single element anomaly shows that Ag,Pb,Zn and Sn elements have large scale strong anomaly. Composite anomaly delineates four anomalies which are divided into two types: Ag—Au—As—Sb anomaly and Bi—W—Pb—Zn-Sn anomaly. All the elements fall into five groups in factor analysis. Thereinto,F1 factor is composed of Ag-Au-As-Sb elements and F2 factor consists of Pb-Zn-Sn elements. On the basis of soil geochemical anomaly characteristics and ore-forming conditions,two ore-prospecting targets have been delineated,of which target BQ—1 is for Pb-Zn-Sn mineralization and target BQ-2 is for Ag mineralization.
