五指山那雍枝铅锌矿位于川-滇-黔铅锌成矿域东侧，含矿层位为寒武系下统清虚洞组，矿体呈层状似层状产出，矿体的产出与分布受地层、岩性、构造控制明显。根据矿床矿体地质特征、矿石矿物特征、区域地质演化与成矿、地球化学特征、控矿因素等要素分析，成矿过程为印支-燕山期造山运动形成的断陷盆地及山间谷地、褶皱虚脱部位、断裂，在造山运动形成的热能活化地层中的 Pb、Zn 等元素，加之大气降水沿裂隙的渗入与地下水混合后形成相对对流，将活化的成矿物质运移到褶皱构造的虚脱部位及断裂破碎带内富集成矿。
五指山那雍枝鉛鋅礦位于川-滇-黔鉛鋅成礦域東側，含礦層位為寒武繫下統清虛洞組，礦體呈層狀似層狀產齣，礦體的產齣與分佈受地層、巖性、構造控製明顯。根據礦床礦體地質特徵、礦石礦物特徵、區域地質縯化與成礦、地毬化學特徵、控礦因素等要素分析，成礦過程為印支-燕山期造山運動形成的斷陷盆地及山間穀地、褶皺虛脫部位、斷裂，在造山運動形成的熱能活化地層中的 Pb、Zn 等元素，加之大氣降水沿裂隙的滲入與地下水混閤後形成相對對流，將活化的成礦物質運移到褶皺構造的虛脫部位及斷裂破碎帶內富集成礦。

Nayongzhi Pb-Zn deposit in Wuzhishan is located at the east side of Sichuan-Yunnan-Guizhou Pb-Zn metallogenetic domain,and its ore-bearing formation is lower Cambrian Qingxudong Group.The ore-bodies are in stratified or stratoid structure,and the occurrence and distribution of the ore-bodies are obviously con-trolled by strata,lithology and structure.According to the geological characteristics of deposit and its ore-bodies,the features of ores and minerals,regional geologic evolution and mineralization,geochemical fea-tures as well as ore-controlling factors,the mineralization process consists of faulting of downfaulted basin formed by Indosinian-Yanshanian orogeny as well as intermontane valley and collapse locations on folds,ele-ments like Pb and Zn in thermal mobilized strata which is formed by orogeny,convection of a mixture of at-mospheric precipitation infiltrated through fissures and underground water,enrichment mineralization of mo-bilized metallogenic material at collapse locations of folding structure and faulted fracture belt.
