This paper has described the effectiveness of gamma spectral survey in prospecting for uranium

deposits within the basin of Hongshan area. Gamma spectral survey data were processed to enhance and

extract faint information of uranium deposits. The anomaly features of gamma spectral survey are high and

exhibit uranium migrationenrichment centers above shallow uranium deposits and gradient zones from high

anomaly to low anomaly above deep uranium deposits. It is therefore concluded that this method is effective

in the prognosis of uranium mineralization in the basin.
