内蒙古古尔班土拉格地区土壤地球化学测量及找矿前景

The Soil Geochemical Survey and Prospecting Potential of Gurbanturag region,Inner Mongolia

通过在内蒙古古尔班土拉格地区的土壤地球化学测量,分析了Li、Be、Co、Ni、Cu、Zn、Nb、Mo、Ag、Sn、Sb、W、Pb、Bi、Th、U、As、Au等18种元素分布特征,圈定了65处综合异常,探讨了找矿前景。结果显示,冲洪积砂砾区元素分异性弱,成矿可能性低;残山区成矿可能性大。聚类分析和因子分析分别将元素分为3个族和简化为4个主要因子,揭示了元素的相互关系和组合特征。3处重要异常查证重现性好,成矿潜力大。经综合分析,划分出4处成矿远景区,优选出铁、钨、铋、铜和钨、钼、铋、铜2处找矿靶区。

Based on the soil geochemical survey in Gurbanturag region,Inner Mongolia,this paper analyzed the distribution characteristics of 18 elements,such as Li,Be,Co,Ni,Cu,Zn,Nb,Mo,Ag,Sn,Sb,W,Pb,Bi,Th,U,As and Au,delineated 65 comprehensive anomalies and discussed prospecting prospects.The results showed the element differentiation was weak and the metallogenic possibility was low in Alluvial-diluvial sandy-gravel area,while the metallogenic possibility was high in residual mountain area.Cluster analysis and factor analysis divided elements into three families and simplified them into four main factors,revealing the relationship and combination characteristics of elements.Three important anomalies had good reproducibility and great metallogenic potential.Through comprehensive analysis,four prospecting areas were divided,and two prospecting targets of iron,tungsten,bismuth,copper and tungsten,molybdenum,bismuth and copper were selected.
