摘　　要：利用西藏一江两河地区东段最新的1∶20万航磁勘查资料,结合现有的地质、物、化、遥成果,用定性与定量相结合的方法对该地区的内生金属矿找矿远景进行了评价,共划出3个级别的找矿远景区28片,并在其中的一、二级找矿远景区中确定找矿靶区21个。这些靶区中均有找矿意义较好的航磁异常,应是今后找矿工作的重点。Based on the newly-obtained 1： 200 000 aeromagnetic survey data in combination with geological, geophysical and geochemical data available, the authors evaluated the ore-searching prospects in the area along the Yarlung Zangbo River and two other rivers of Tibet. 28 promising areas were detected which can be divided into three grades, and 21 ore targets were delineated within the 1st and 2nd grade areas. Fairly good aeromagnetic anomalies lie in these targets, and hence these targets deserve much attention in further oreprospecting work.
