摘　　要：为了在尼日尔Azelik铀矿已知砂岩型铀矿床周边及外围地区寻找新的铀矿化线索,开展了土壤氡气测量方法试验及应用。在已知剖面上的试验结果表明,土壤瞬时测氡结果反映了深部铀矿化信息,在北部、中部和西部3片测区共发现较大规模的土壤氡气异常共4片,为地质找矿工作提供了参考依据。Application and experiment of soil radon survey were carried out in order to find a new clue of uranium mineralization around the known sandstone type uranium deposit in Azelik, Niger. Deep mineralization information was well reflected by the experimental results. Four large scale soil radon anomalies were found in the northern, central and western areas, which may provide the reference for the further study of geological prospecting work.
