综合物探方法在粤北长江矿田的勘查效果及找矿意义——以书楼丘(305)铀矿床为例

The Exploration Effect and Significance of Comprehensive Geophysical Prospecting Method in Changjiang Orefield of Northern Guangdong,a Case Study of Shulouqiu Deposit

粤北长江矿田新一轮铀矿找矿主要针对深部隐伏铀矿。在书楼丘(305)铀矿床典型剖面上开展壤中氡法、音频大地电磁测深法与激电测深法工作,推断解释了1条找矿前景较大的隐伏断裂。工作成果还表明,3种物探方法在已知断裂上均有不同程度的响应,书楼丘(305)矿床深部赋矿环境良好,指示其深部具有很好的找矿潜力。

The new round exploration in Changjiang Orefields of Northern Guangdong aims to find uranium deposit in the deep.Three survey methods of soil Rn,AMT and induced polarization sounding were carried out in the typical section of Shulouqiu（305）deposit.one large concealed fault was interpreted and inferred with great prospecting potential.The result also showed that the three methods have different response to the known faults and indicated that there is very good prospecting potential in the deep of Shulouqiu（305）deposit.
