赣南崇义石咀脑钨矿区土壤地球化学特征分析及找矿效果

Soil Geochemical Characteristics and Ore-Search Effect of the Shizuinao Tungsten Mine Area,Chongyi,South Jiangxi Province

赣南崇义石咀脑钨矿位于江西省崇义县黄竹垅-长流坑钨锡多金属矿田的南部,具有较大找矿潜力。本次在野外调查的基础上,对石咀脑勘查区矿区进行了1∶10000土壤地球化学测量。选取与赣南地区钨锡成矿关系密切的Cu、Pb、Zn、Sn、Ag、W、Mo、As、Sb、Au等10种元素进行测试,并对数据和相关参数分析,结果显示:石咀脑钨锡矿区W、Sn、Cu是主要成矿元素;根据成矿地质条件和元素的异常分布特征,在石咀脑矿区圈定出2处找矿靶区,经钻探揭露出钨矿石英脉带,找矿效果良好,为后续探矿进一步工作提供了依据。

The Shizuinao tungsten deposit with a great prospecting potential is located in the south of the Huangzhulong-Changliukeng tungsten-tin polymetallic ore field in Chongyi County of South Jiangxi Province.Based on the field investigation,the soil geochemistry survey of 1∶10000 was conducted in the Shizuinao exploration area.Ten elements,including Cu,Pb,Zn,Sn,Ag,W,Mo,As,Sb and Au,which are closely related to the tungsten-tin mineralization in southern Jiangxi,were analyzed.Results show that W,Sn and Cu are the main ore-forming elements in the Shizuinao tungsten-tin mineralization area.According to the metallogenic geological conditions and the anomaly distribution characteristics of elements,two prospecting target areas were delineated in this mining area.And tungsten quartz vein zones were revealed by drilling,implying a good prospecting effect,which provides a basis for further exploration in the future.
