Based on Keyue Pb-Zn-Sb polymetallic deposit in Tibet ,through the research on the field geological investi-gation and indoor data processing, generally understand its geological characteristics. And on this basis, the primary halo prospecting theory and method to study the metallogenic elements and indicator elements within the mining area. The study includes the zoning sequence of elements, assemblage characteristics, anomalous element relation with mineraliza-tion etc.. The author conducted a preliminary metallogenic prediction of Keyue mining area, established the primary halo tectonic metallogenic model, we draw the following conclusions: on the basis of the modified C.B. Grigorian method can be as follows: zoning sequence (top-down), Mo-Ni-Au-Bi-As-Hg-Pb-Ag-W-In-Cu-Ba-Ga- Zn-Sb. Front Keyue mineral-ization indicating elements are Hg, Ba, Sb, As, Keyue deposit ore near indicating elements are Pb, Cu, Ag, Zn, Au, metal-logenic Keyue lead antimony polymetallic deposit tail halo indicating elements are W, In, Mo, Bi, Ga, Ni. Also reflects the characteristics of Keyue lead antimony polymetallic deposit multistage mineralization, variation characteristics of geochemical parameters of axial showed a deep blind ore bodies occur.%基于藏南隆子县柯月铅锌锑多金属矿床地质特征，运用原生晕找矿方法研究该矿区成矿元素和指示元素。通过元素分带序列、组合特征，异常元素与成矿关系等，对柯月矿区进行初步成矿预测，建立构造原生晕成矿模型。据改良C.B.格里戈良方法得到如下分带序列（自上而下）：Mo-Ni-Au-Bi-As-Hg-Pb-Ag-W-In-Cu-Ba-Ga-Zn-Sb。柯月矿床成矿前缘指示元素为Hg，Ba，Sb，As，成矿近矿指示元素为Pb，Cu，Ag，Zn，Au，成矿尾晕指示元素为W，In，Mo，Bi，Ga，Ni。前缘与尾晕元素叠加现象反映了该矿床多期次、多阶段成矿特征，地球化学参数轴向变化特征显示深部盲矿体的存在。
