摘　　要：中高山地区是我国金属矿产重要勘查区和接替基地,为了寻找一种找矿快速突破的有效手段,中国国土资源航空物探遥感中心在西部中高山区开展了大比例尺高精度航磁调查实践,采用高精度的航空物探测量系统和随地形缓起伏的飞行方法获得了高质量的原始数据,通过详细的物性资料分析与深入细致的异常解释工作,结合快速地面查证手段实现了中高山地区找矿工作的快速突破,开创了航空物探找矿工作的新局面。从已完成的航磁调查工作与找矿效果看,中高山地区高精度航磁调查具有速度快、精度高、费用低和效果显著等特点,具有广阔的应用前景和推广价值。In order to find an effective means for quick prospecting breakthrough in middle and high mountain areas of West China, which are believed to be the most important mineral exploration areas and replacement bases, China Aero Geophysical Survey and Re- mote Sensing Center for Land and Resources carried out large-scale aeromagnetic survey in high mountain areas. With high-precision measurements and slow undulating flight in accord with the terrain, qualified raw data were acquired. It was followed by detailed mag- netic analysis of rocks, intensive interpretation of anomalies, and fast ground inspection, which made it possible to find a series of met- al minerals, thus opening up a new prospect for aeromagnetic survey. According to the test survey and the prospecting effects, the large-scale aeromagnetic method has the advantages of rapidness, high precision, low cost and significant effect in middle and high mountain areas, thus having broad application prospect as well as promotional value in these areas.
