1∶2.5万沟系岩屑测量的找矿效果和工作方法探讨

1:25,000 debris survey of the valley system and working methods of prospecting effect

沟系岩屑测量是一种在干旱、半干旱荒漠地区以岩石碎屑为采样对象非正规网的地球化学找矿方法,该方法在矿产资源评价工作中,能够快速缩小找矿靶区,对找矿起到了较好的指导作用。笔者根据多年来在异常查证工作中对该方法的应用,从野外采样点位图编制、野外样品的采集、异常等值线圈定及综合异常图的编制等几个方面对1:25000沟系岩屑测量工作方法进行了探讨,提出了应该注意的事项。

The groove debris geochemical survey is the geochemical prospecting method which is suitable to pick debris with non -formal network in the arid, semi- arid desert regions. The method can quickly locate the target in the prospecting area, which is helpful for prospecting. The authors discuss the methods in the process Of designing, practicing, analyzing, giving result and others and propose something that should be paid attention to in the debris geochemical survey.
