新疆五峰山火烧云式喷流-沉积型铅锌矿的发现——勘查地球化学找矿成功案例

The Discovery of the Huoshaoyun Type Spout-Sedimentary Lead-Zinc Deposit in Wufengshan,Xinjiang--A Successful Case of Geochemical Prospecting

五峰山铅锌矿是在优选1∶50万化探异常的基础上,开展1∶5万水系沉积物测量缩小异常,利用1∶1万岩石剖面测量查证异常,进一步缩小靶区,获得重要发现。通过深部钻探验证,矿床达中型,实现了火烧云铅锌矿外围同类型矿床的找矿突破。该矿床的发现表明,利用勘查地球化学找矿方法,逐步聚焦异常查证,能有效提高找矿效率。同时证实了喀喇昆仑中生代沉积盆地中大面积出露的中侏罗统龙山组碳酸盐岩层位具寻找火烧云式铅锌矿的良好潜力,对区域找矿具有重要示范意义。

Exploration geochemistry is an important prospecting method.On the basis of optimizing 1:500,000 geochemical anomalies,Wufengshan leadzinc mine carried out 1∶50,000 stream sediment survey to reduce anomalies,and used 1∶10,000 rock profile survey to verify anomalies,so as to further reduce the target area and obtain important discoveries.Through deep drilling verification,the deposit reaches mediumsized,and the prospecting breakthrough of the same type deposit in the periphery of Huoshaoyun leadzinc mine is realized,and the prospect is considerable.The discovery of the deposit shows that the use of geochemical prospecting methods to gradually focus on anomaly verification can effectively improve the prospecting efficiency.At the same time,it is confirmed that the carbonate strata of the Middle Jurassic Longshan Formation exposed in a large area in the Mesozoic sedimentary basin of Karakoram has a good potential for searching for the firetype leadzinc deposit,which has important demonstration significance for regional prospecting.
