土壤氡气测量在核桃坝铀矿勘查中的应用与研究

The application and research of radon measurement in the uranium exploration, He Taoba area

核桃坝地区位于内蒙古锡林郭勒盟,是我国近年来在北方发现的少数铀矿床之一。为进一步挖掘潜力,扩大找矿范围,寻找隐伏构造和隐伏铀矿体已经成为该区今后的主要任务。论文利用已知地质特征和铀矿化条件,通过土壤氡气测量方法,寻找核桃坝地区的隐伏构造和隐伏铀矿体。经过钻孔验证,在钻孔深部中发现了铀工业矿体和构造破碎带,进一步验证使用土壤氡气测量方法在寻找隐伏构造和隐伏铀矿体方面行之有效。

HeTaoba area is located in County,Xilin Gol League,Inner Mongolia.It’s one of the few uraniumdeposits which were found in North China in recent years.In order to further explore the potential and expand therange of exploration,it has become the main task of the area which searching concealed structures and concealed uraniumore bodies.The paper whose research object is HeTaoba area,looks for controlling structures and concealed uraniumore bodies of HeTaoba area,through the soil radon measurement,combining with the known geological featuresand uranium mineralization conditions.After Borehole verification,we found the uranium ore bodies and structuralfracture zone in deep boreholes.Using soil radon measurement is effective in finding the Concealed structure and uraniumore bodies.
