西藏一江两河地区高精度航磁勘查效果

Results of high-resolution aeromagnetic surveys in the Yarlung Zangbo River area

中国国土资源航空物探遥感中心于2000—2001年在西藏一江(雅鲁藏布江)两河(拉萨河、年楚河)地区开展了1∶20万～1∶25万高精度航磁勘查,发现一批具有找矿意义的异常、一组北西向断裂及其他构造形迹,为基础地质研究、1∶25万区域地质调查和矿产资源勘查评价提供了高精度的地球物理资料。

The Airborne Geophysical Remote Sensing Center,Ministry of Land and Resources,carried out 1∶200000～1∶250000high-resolution aero magnetic surveys in the area along the Yarlung Zangbo River and other two rivers and found a number of anomalies,a northwest set of faults and other structures fea-tures which were of mineral prospecting significance,providing high-resolution geophysical data for the fundamental geological research,1∶250000regional surveys and mineral exploration and exploitation.
