摘要
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 examples,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.
