摘要
文中简要介绍了氡气测量和土壤天然热释光测量(TL)野外样品采集及室内样品分析的工作方法和应注意的事项。对下庄花岗岩型铀矿床的初步研究结果表明:(1)在硅化破碎带型铀矿体上方,氡气测量的高值异常主要反映构造破碎带在地表的出露位置,土壤天然热释光测量的高值异常则主要反映铀矿体的位置,当两种方法的异常重合时,找到铀矿体的可能性较大;(2)在“交点”型铀矿体上方,氡气测量的高值异常同样反映了构造破碎带在地表的出露位置,而土壤天然热释光测量的高值异常则反映了构造破碎带与中基性岩脉的交线处为铀矿体的赋存位置。
This paper briefly introduces the methods and procedures for field and indoor radon survey and themoluminescence (TL) survey. The application of these two methods to Xiazhuang uranium field in Guangdong province shows: (1) the positive anomalies of radon survey coincide well with fractured zone and the positive anomalies of TL survey response to uranium mineralization on granite type uranium deposit of silicated fracture zone, the uranium deposit can be effectively explored when these two kinds of anomalies match together. (2) the positive anomalies of radon survey coincide well with fractured zone and the positive anomalies of TL response to the position that intersection between the fractured zone and diabase dyke is projected on the ground.
