摘　　要：岩(矿)石电磁、磁、放射性质的差异是航空物探(电磁、磁、放)测量的前提和地质解释基础。本文从航空电磁、航磁、航空伽玛能谱测量的基本原理出发,着重介绍了不同航空物探异常圈定的原则,并以实例的方式,分别对航空电磁法所反映的蚀变带、航磁反映的隐伏岩浆岩以及航空伽玛能谱反映的断裂带等方面进行了分析,研究了其与成矿的关系。最后,以一处航空物探综合异常为例,对综合解释方法进行了较详细的介绍,明确了该异常是今后找矿的重要标志。Rock （ore） property difference in electric magnetic magnetic and radiotion are the procondition of airborne geophysical survey and the foundation of geological explanation. According to the basic principles of AEM, aeromagnetic and airborne gamma ray spectrometry, the principles of different airborne geophysical anomalies determination are introduced. The alteration zone reflected by AEM, concealed rocks reflected by aeromagmetic and fracture tectonic belt reflected by airborne gamma spectrometry are studied by practical ex- amples, the relation with mineralization is also studied. Finally, the comprehensible explanation method is introduced in details by example of a comprehensible airborne geophysical anomalies, the anomalies is sure an important indicator for future exploration.
