化探方法在贵州晴隆大厂矿集区锑矿找矿中的应用

Application of geochemical exploration method in antimony prospecting in Dachang ore concentration area,Qinglong,Guizhou

本次研究以《贵州晴隆大厂矿集区找矿预测》项目为基础,系统梳理了化探方法在锑矿找矿中工程运用。研究首先以1:5万水系沉积物测量圈定了系列的Au-Sb-W-As-Sb-W-F-Ag组合异常。通过岩石地球化学剖面分析了元素的分带性,并初步确定了成矿热液沿构造运移,在此基础上使用构造地球化学方法寻找有利靶区。通过钻探验证证明了化探方法在黔西南锑矿找矿中的有效性,为该区域锑矿找矿方法进行了有益的探索。

Based on the project"prospecting prediction of Dachang ore concentration area in Qinglong,Guizhou",this study systematically combs the engineering application of geochemical exploration methods in antimony prospecting.Firstly,a series of au-sb-w-as-sb-w-f-ag assemblage anomalies are delineated by 1:50000 stream sediment measurement.The zoning of elements is analyzed through the rock geochemical profile,and the migration of ore-forming hydrothermal solution along the structure is preliminarily determined.On this basis,the structural geochemical method is used to find the favorable target area.Through drilling verification,the effectiveness of geochemical exploration method in antimony prospecting in Southwest Guizhou is proved,which is a beneficial exploration for antimony prospecting method in this area.
