【摘要】 测氡方法是寻找深部隐伏矿的一种放射性地球物理方法。在川西田湾大发沟矿床，由于金矿化严格受剪切带和辉绿岩脉控制，且剪切带与辉绿岩脉密切伴生，因此，应用测氡方法寻找剪切带和辉绿岩脉可以达到间接找金矿的目的。更多还原

【Abstract】 Radon measurement technique is a radiometric geophysical method in search for deep concealed deposits.In the Dafagou deposit of Tianwan,western Sichuan,gold mineralization is strictly controlled by shear zones and diabase dikes,and shear zones are closely associated with diabase dikes.Hence the application of radon measurement method to the search for shear zones and diabase dikes can achieve the aim of indirect prospecting for gold deposits.更多还原
