摘要
氡及其子体测量用于寻找砂岩型铀矿床上能够形成清晰的异常,但氡及其子体测量方法较多且各具有不同的特点。总结几种常用的氡及其子体测量方法在砂岩型铀矿上的异常特征,并进行比较分析,结果表明铀矿体所在部位大都具有明显的负异常特征,而矿体的头、尾部多呈正异常,其中累积测量比瞬时测量的异常特征更加明显,对应钻孔的位置更好。
Clearly abnormity can be obtained when using the radon and its daughters survey in prospecung for sandstone-type uranium deposits. But there are several survey methods with different features. This paper summarizes abnormity characteristics, f the radon and its daughters survey in sandstone-type uranium deposits, and then analyzes their difference. The result showes that there are distinctly negative anomalies above the body of sandstone-type uranium deposits, whereas positive anomalies is on the top and end of ore body, and the accumulate methods are more effective than instantaneous methods for abnormity feature.
