摘要
为了提高航磁在西藏一江两河地区的找矿效果,深入研究了2000～2004年间中国国土资源航空物探遥感中心在该区开展的1∶20万～1∶25万高精度航磁调查资料,对一批具有找矿意义的航磁异常,经地面踏勘,总结了航磁局部异常与矿产的对应关系,阐述了利用航磁资料直接找矿的效果,为该地区的地质找矿工作提供了帮助。
In order to improve the ore-prospecting effect of aeromagnetic survey in ＂Yijianglianghe＂（one large river and two other rivers） region of Tibet,the authors thoroughly studied the 1∶200 000 high-precision aeromagnetic data obtained in this region by China Aero Geophysical Survey and Remote Sensing Center for Land and Resources and made field reconnaissance in areas of significant aeromagnetic anomalies.On such a basis,this paper sums up the correlation between aeromagnetic local anomalies and ore resources and recounts the effect of direct application of aeromagnetic data to ore-prospecting work,which is helpful to geological ore-prospecting work in this region.
