摘要
In order to distinguish anomalies related to uranium deposits from many radiometric survey anomalies caused by such factors as lithology,structure and alteration in granite area,the authors used magnetic survey in search for fractured zones,and utilized radon concentrations of active Carbon survey as well as pit gamma ray spectral survey to recognize deep anomalies related to uranium deposits.It is found that economic uranium ores are included on the dip side of the ore-control fractured zones,as evidenced by drilling verification.
