土壤氡气法与分量化探法联合探寻深部隐伏铀矿

摘要

介绍了土壤氧气测量和分量化探测两种探寻深部隐伏铀矿的探测方法.在已知隐伏铀矿体上方,土壤氧气异常显示赋矿区域具有较佳的赋矿环境;分量U与分量Mo、W、Ni、Cd等元素组合异常;土壤氡气与分量化探所有元素的相关性系数均小于0.5,表明土壤氧气与分量化探所有元素的相关性不显著;分量U与分量Mo、W、Bi、Ni、Cd、Cu、Zn、Ba元素的相关性系数分别为0.52、0.55、0.56、0.57、0.89、0.68、0.82、0.57,表明分量U与上述分量元素相关性显著.土壤氡气测量能有效识别(隐伏)断裂带,分量化探测量能直接捕获深部铀矿信息.%This paper introduces two methods of soil radon measurement and component of the geochemical measurement on deep concealed uranium deposits.Above the known concealed uranium ore body,Soil anomaly shows that the area has better occurrence condition;U element of component geochemical and Mo,W,Ni,Cd elements of component geochemical are composite anomalies;the correlation coefficients of soil and geochemical elements were all less than 0.5,indicating that soil radon and elements of component of the geochemical measurement were not significant;but the correlation coefficients of U and Mo、W、Bi、Ni、Cd、Cu、Zn、Ba elements of component geochemical were0.52,0.55,0.56,0.57,0.89,0.68,0.82,0.57,which showed that the correlation between U elements and the above elements was significant;soil Rn measurement can effectively identify (concealed) crack,and component of the geochemical measurement can directly capture the information of deep uranium deposits.
