摘要
论述了坑内伽马能谱测量在盆地内寻找近地表铀矿以及预测深部铀矿可能发育部位的应用实例。坑内伽马能谱测量数据经过多参数组合处理和微弱信息提取,分析了坑内伽马能谱放射性异常与铀矿体位置的关系,异常特征在浅地表工业铀矿体上方表现为铀异常区和铀迁移富集中心,在深部铀矿体上方表现为铀高场向铀低场过渡的梯度带。因此,对于寻找盆地内近地表铀矿以及预测深部铀矿可能的发育部位,坑内伽马能谱测量可以作为一种寻找铀矿的有效方法。
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.
