青海省都兰县拉浪麦钨矿的勘查过程及工作建议

The Discovery Process and Work Suggestions of Lalangmai Tungsten Mine in Dulan County,Qinghai Province

研究前人资料基础上,采用1:1万荧光地质填图+1:1万土壤地球化学测量等工作手段,对拉浪麦圈定HS乙367WSb综合异常,利用探槽工程揭露、查证,寻找矿化地段;对已发现矿体利用探槽工程控制,扩大矿体规模,择优矿化富集地段利用钻探工程进行深部验证,了解矿体深部变化特征,实现了拉浪麦地区钨矿找矿突破。建议今后在东昆仑成矿带新一轮找矿突破工作部署中,加大对W、Sb等元素组合异常查证工作,为钨多金属矿的找矿提供参考。

On the basis of previous research data,using 1:10000 fluorescence geological mapping+1:10000 soil geochemical survey and other working methods,the comprehensive anomaly of HS乙_(3)^(67) WSb was delineated in Lalangmai,and the mineralized area was revealed and verified by trench engineering.The discovered ore bodies are controlled by trench engineering,the scale of ore bodies is expanded,and the deep verification is carried out by drilling engineering in the preferential mineralization enrichment area to understand the deep variation characteristics of ore bodies,and the prospecting breakthrough of tungsten deposits in Lalangmai area is realized.It is suggested that in the new round of prospecting breakthrough work deployment in the East Kunlun metallogenic belt,the verification of W,'Sb and other element combination anomalies should be strengthened to achieve the prospecting breakthrough of tungsten polymetallic deposits.
