The well-known 1 Sichuan Yunnan Guizhou Triangle (SYGT) area of poly-metallic Zn-Pb deposits, southwest China is located at the south-western margin of the Yangtze Block in the transition area of the Tethys Belt and the Circum-Pacific Metallogenic Belt, and is composed of the Northeastern Yunnan, Northwestern Guizhou and Southwestern Shichuan Deposit Concentration Districts. More than 450 Zn-Pb deposits and ore occurrences are spread in the delta area enclosed by the NS-trending Xiaojiang fault belt, the NW-trending Kangding–Shuicheng fault belt and NE-trending Mile–Shizong fault belt. There are many large-scale to super-large-sized high-grade rich (Ge-Ag)-Zn-Pb deposits in the world. E.g. Huize, Maoping, Lemachang, Maozu, Lehong, Jinshachang, Fulechang, Tianbaoshan, Xiaoshifang deposits, etc. In these deposits, the Huize deposit is one of the richest Zn-Pb deposits in the world. SYGT is great potential area to find rich and large deposits, and becomes the most frontier hotspots in geoscience research. It is the largest Zn-Pb industry base in China, and has been listed as one of the 16 major exploration areas of national resource planning. On the basis of summarizing the unique characteristics of deposits in SYGT (Han et al., 2007, 2012), the metallogenic regularities of deposits have briefly summarized, and the new deposit type has been proposed. *
