The northeast of Yunnan Pb-Zn-Ag-Ge polymetallic ore district is an important part of the southwestern margin of the Yangtze block Sichuan-Yunnan-Guizhou Pb-Zn polymetallic metallogenic domain, located in the east of Xiaojiang deep fault and in the southern part of Yunnan northeast depression basin, the distribution of the SN trending Xiaojiang deep fault zone and the NW trending Ziyun yadu deep fracture zone and the NE-trending Maitreya Shizong deep fault zone surrounded by the "triangle", adjacent to the Longmen orogenic belt, the Nanpanjiang-Youjiang Hyperplasia of arc fold belt and Mojiang of Ailao Mountain Lvchun orogenic belt. Because of multi tectonic superposition, strong geological environment change and the mechanism of metallogenic dynamics complex, metallogenic geological conditions are superior, not only the formation of China's unique germanium rich lead-zinc polymetallic ore district, and creating a super high grade rare in the world (Pb+Zn:25% ~ 35%) large super-large germanium rich zinc silver polymetallic deposit is typical in the Sichuan-Yunnan-Guizhou a lead-zinc polymetallic metallogenic domain(Han Runsheng,2014). The Huize lead-zinc mine is composed of two lead zinc deposits in the Kuangshanchang and Qilinchang. Ore district strata by the composition pre-Sinian metamorphic basement, the Sinian and Paleozoic sedimentary cover. The rocks exposed in Huize lead-zinc mine area consist of the complete upper palaeozoic, Cambrian Qiongzhusi group formation, a part of Upper Sinian Dengying Formation, strikes NE and dips NW Lower Carboniferous Series baizuo formation that a wide range of area and the main ore-hosting strata. The structure of
