Abstract: The metallogenic belt in the south of SE Yunnan is one of the important polymetallic belts in Yunnan Province. In this belt, such polymetallic sulfide deposits as Sn, W, Pb, Zn, Ag are mainly hosted in the clastic and carbonate rock formations of Cambrian, Devonian, Permian and Triassic, and distributed around three large granitic intrusions, Gejiu, Bozhushan and Laojunshan. Fifty three Tintungsten and other metal deposits have been found in recent years by ore exploration in the area. Based on studies of geology, geochemistry and metallogenic regularity of known deposits in the area, such four typical deposits, Kafang Cu-Sn, Nanyangtian W, Bainiuchang Pb-Zn-Ag and Xiaoxiban Sb deposits, have been analyzed. According to favorable geological conditions, geochemical anomalies, five ore prospecting regions are defined, including Gejiu Sn-W-Cu, Bozhushan-Bainiuchang W-Pb-Zn-Ag, Laojunshan-Malipo W-Sn, Yanshan Cu-Pb-Zn, Xichou Sb ore prospecting regions. The forecasted resource reserves, includes 1.33 million tons of Sn, 1.12 million tons of WO3, 9.42 million tons of Pb and Zn, 3.26 million tons of Cu as well as 0.3 million tons of Sb. It can be concluded that there is great tintungsten and other metals ore prospecting potential in this area.

Key words: polymetallic metallogenic belt in south of SE Yunnan, ore deposits, ore prospecting field, ore prospecting potential
