摘要: 在南山坑矿区1∶1万土壤地球化学测量成果资料的基础上,初步总结了该区W、Sn、Bi 等13种元素地球化学特征,发现该矿区成矿元素W、Sn及伴生元素Bi、As、Mo等元素高度富集,其中W平均值为117.3×10-6,峰值达7 444.2×10-6,Sn平均值为56.4×10-6,峰值达2 245.9×10-6;数理统计显示南山坑矿区W、Sn、Mo等元素之间相关性较强;R型聚类分析显示矿区元素组合主要有W-Bi-Sn-As、Cu-U-Pb等。本次工作在区内圈定了2个以W-Sn 为主呈带状、东西向分布的松岗梗—牛角窝与富背坳—沙木窝组合异常,浅部探槽揭露和深部钻探验证中均取得了较好的效果,找到了多个矽卡岩型钨锡多金属矿体及花岗岩型钨钼多金属矿体,显示了该区具有较好的钨锡多金属矿找矿前景,为该区下一步找矿工作指明了方向。

Abstract: According to the 1:10,000 pedogeochemical survey results of Nanshankeng ore deposit,the geochemical characteristics of 13 elements such as W,Sn,Bi are summarized preliminarily.The results show that W,Sn and associated elements such as Bi,As,Mo are enriched in the mining area,the average value of W is 117.3×10-6 with peak value of 7 444.2×10-6,and the average value of Sn is 56.4×10-6 with peak value of 2 245.9×10-6.The statistics indicates that the correlation among elements of W,Sn,Mo is strong and according to the R-cluster analysis results,main element association include W-Bi-Sn-As and Cu-U-Pb.There are 2 composite anomalies mainly which are Songganggeng-Niujiaowo and Fubeiao-Shamuwo with W-Sn belt and EW direction,and both of them acquired a good prospecting result by adopting the exposition of shallow prospecting trench and the verification of deep exploration drilling method.So,multiple skarn type tungsten tin polymetallic ore body and granite type tungsten molybdenum polymetallic ore body are found.The favorable prospecting potential of tungsten-tin polymetallic mineral deposit is indicated,thus guiding a further prospecting direction in the mining area.
