The Bangong Co-Nujiang metallogenic belt is one of the most important metallogenic belts in Tibet. Its geochemical characteristics of LongbakangdongKangjia section at Buzicun village are analyzed based on the result of 1∶50 000 stream sediment survey

including distribution and anomaly characteristics of ore-forming elements on the surface

and the characteristics of anomaly element combination. The results show that metal anomaly occur in combination of multiple metal elements

and the highest anomaly is Au-Cu combination

the second is front elements combination of As-Sb-Ag-Cd-Pb

then rear element combination of Bi-W-Mo. The anomaly areas of front elements

ore-forming elements

and rear elements are distributed from west to east

and the halos have good zonation

suggesting that there may be a porphyritic type Cu-Au deposit in study area

and  Longbakangdong-Kangjia anomaly area may be a potential area for prospecting large copper-gold deposit.
