摘　　要：自采用液体捕集剂以来,经过试剂提纯、使用超净环境和捕集装置的改进,地气观测精度得到很大提高,不仅证实了隐伏矿上方地气金属元素异常存在,而且在实际找矿中获得了很好的找矿效果。通过介绍黄土覆盖和冲积平原区隐伏金属矿矿床上方地气元素分布特征,说明地气测量能够用于该类条件下隐伏矿勘查,可望为类似景观区矿产勘查提供有效地球化学手段。Since the adoption of liquid trapping agent, the observation accuracy of geogas has been greatly improved through purifica- tion of reagents, utilization of super-clean environment and improvement of the collecting device. Geogas anomalies appear over concealed deposits, and a favorable effect is obtained in ore prospecting. This paper describes the features of geogas element distribution over concealed metallic deposits, in loessial overburden areas and on alluvial plains. Geogas survey is an effective geochemical means and can be used in search for concealed deposits in similar landscape areas.
