Abstract: Bangzhuoma area in Southern Tibet is located in the east-central part of Tethys Himalayas and situated in the Jiangzi-Longzi gold-antimony polymetallic metallogenic belt in Southern Tibet.Bangzhuoma area in Southern Tibet has great metallogenic potential and it is a favorable area for the exploration of gold-antimony polymetallic deposits.In order to achieve prospecting breakthrough in the area，some relative geological prospecting work is conducted，based on 1∶10 000 soil geochemical measurement data of the area，the integration method of element variation coefficient，variation coefficient interpretation diagram of Cv1 and Cv1 /Cv2，and fractal theory is adopted to analyze the nine elements of Au，Pb，W，Sb，Cu，Zn，Mo，Ba and Sn，the spatial enrichment distribution regularity and metallogenic potential of them are revealed.Based on the above discussion results，metallogenic prediction work is done based on metallogenic geological condition and element anomaly characteristics.The study results show that:①metallogenic potential of Cu，Zn，Mo，Ba and Sn is less than that of Au，Pb，W and Sb，and the abnormal lower limit values of the elements are obtained with value of Au 7.24×10^-9，value of Pb 53.83×10^-6，value of W 6.12×10^-6，value of Sb 4.14×10^-6；②according to element correlation relationship，three prospecting target areas in the Bangzhuoma area are delineated，Au is the main mineral in 1# prospecting target area，and its abnormal strength is 36.4×10^-9，abnormal strength of Au in 2# and 3# prospecting target area are 49.8×10^-9 and 47.3×10^-9；③through trench engineering verification of 1# prospecting target area，a gold-bearing quartz vein with length of 150 m and thickness of 0.30 m is found，with Au grade of （3.64~4.78）×10^-6；Au abnormal strength in 2# and 3# prospecting target area are both higher than that of 1# prospecting target area，which further show that prospecting potential in Bangzhuoma area is good.
