摘　　要：列举了土壤天然热释光测量在红山地区盆地内预测铀矿化可能发育部位的应用实例。通过开展土壤天然热释光测量及其数理统计,分析了土壤天然热释光异常与铀矿体位置的关系,异常特征表现在铀矿体上方为低值异常,在非矿区为高值异常,而在花岗岩蚀源区则表现为高场异常。因此,土壤天然热释光低值异常区可能为铀矿发育部位。此法可作为盆地内铀矿找矿的一种有效方法。A case of forecasting the possible location where the uranium mineralization might have been developed using soil natural thermoluminescence survey in a basin of Hongshan area is laid. Based on developing soil natural thermoluminescence survey and mathematical statistics, the relationship between the soil natural thermoluminescence anomaly and the uranium orebody location is analyzed. It is founded that anomaly character above uranium orebody is of low value and high value above non-uranium deposit area. However, the anomaly in granite provenance area shows high field character. Hence, soil natural thermoluminescence survey with low value anomalistic area can forecast the location of uranium orebody and this method can be used as an effective method to prospecting uranium deposits in a basin.
