青海玛沁县曲赫地区地球化学方法找矿效果分析

Analysis of the prospecting effect of geochemical method in Quhe area, Maqin County, Qinghai Province

青海玛沁县曲赫地区实施了1:20万水系沉积物工作,通过少量样品分析成果,快速掌握了元素富集信息,在此基础上,进一步开展1:5万水系沉积物测量、1:1万土壤地球化学测量、1:5千土壤-地质剖面,结合地质、少量槽探圈定多条金、钨、铜矿体,表明了地球化学方法在该地区寻找金、钨、铜矿的有效性、准确性。

In Quhe area of Maqin County,Qinghai Province,1:200000 stream sediment work has been carried out.Based on the analysis results of a small number of samples,the information of element enrichment has been quickly grasped.On this basis,further 1:50000 stream sediment survey,1:10000 soil geochemical survey and 1:5000 soil geological profile have been carried out.Combined with geology and a small amount of trenching,many gold,tungsten and copper deposits have been delineated,which shows that The validity and accuracy of geochemical methods in searching for gold,tungsten and copper in this area.
