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 ore-prospecting work.
