为了快速缩小找矿靶区，缩短找矿周期，提高找矿工作效率，在龙门店银矿区开展了1∶10000沟系次生晕土壤地球化学测量扫面工作。通过分析，共圈定出19处综合异常，并在后续的异常查证中发现了多个金、银多金属矿体，取得了显著的找矿效果。实践表明，在土壤盖层和沟系发育、没有次生污染地区，排除可控的干扰因素开展沟系次生晕测量工作，对比采用正规网土壤测量，可以较少的样品数量控制较大的面积达到基本一致的找矿目的，由此可以认为，沟系次生晕测量是一种非常有效和便捷的地球化学找矿方法。
In Longmendian silver mining area,in order to quickly narrow prospecting targets,shorten prospecting cycle and improve exploration efficiency,1∶10 000 soil geochemical survey of secondary halo measurement of ravine system is deployed in Longmendian Silver Mine District.Through analysis,a total 19 anomalies are delineated and in following verification are found many gold and silver polymetallic orebodies,achieving significant prospecting effects. Practice shows that the soil cap and ravine system develop,and there is no secondary pollution in the region.Relatively less samples can be used to manage a greater area reaching basically consistent results when carrying out the survey work with the exclusion of controllable disturbances and the employment of regular gridding soil measurement.It is concluded that the secondary halo measurement of ravine system is a very effective,convenient geochemical prospec-ting method.
