赣南崇义碧坑钨矿区土壤地球化学特征分析及探矿效果

Soil Geochemical Characteristics and Prospecting Effect of Chongyi Bikeng Tungsten Ore Area in Southern Jiangxi

赣南崇义碧坑钨矿勘查区位于江西崇义县黄竹垄-长流坑钨锡矿田东部,具有较大找矿潜力。在野外调查的基础上,对碧坑勘查区进行了1∶10000的土壤地球化学测量,选取赣南地区与钨锡成矿关系密切的Cu、Pb、Zn、Sn、Ag、As、W、Mo、Au等9种元素进行测试,并对样品所测试数据和相关参数进行分析,结果显示:碧坑钨锡矿区W、Sn、Cu、Ag、Mo为主要成矿元素;依据成矿地质条件及元素异常分布特征,在碧坑矿区圈定出2处有利找矿靶区,经钻探揭露出钨矿石英脉带,找矿效果良好,为后续找矿进一步工作提供了依据。

The Chongyi Bikeng tungsten deposit exploration area in southern Jiangxi Province is located in the east of Huangzhulong-Changliukeng tungsten and tin ore field in Chongyi County,Jiangxi Province,which has great potential in prospecting.On the basis of field investigation,the soil geochemical survey of 1∶10000 was carried out in the mining area of Bikeng exploration area.Nine elements,including Cu,Pb,Zn,Sn,Ag,As,W,Mo and Au,which are closely related to tungsten-tin mineralization in southern Jiangxi,were selected and tested.The data and related parameters of the test results were analyzed.The results show that W,Sn,Cu,Ag and Mo are the main ore-forming elements in Bikeng tungsten-tin ore area.According to the metallogenic geological conditions and the anomalous distribution characteristics of elements,two favorable prospecting target areas were delineated in Bikeng mining area,and tungsten quartz vein zone was revealed by drilling.The prospecting effect is good,which provides a basis for further prospecting work in the future.
