摘　　要：湖南上堡地区位于南岭成矿带西段,面积约2700 km^2,是南岭成矿带的重要组成部分,其中出露有塔山岩体、大义山岩体和上堡岩体,构成了塔山—大义山—上堡东西向构造—岩浆带。综合研究工作区成矿地质条件和已知矿床的特征,预先建立了"黄沙坪式"矽卡岩型铅锌银铜矿矿床模式、"柿竹园式"矽卡岩型钨锡多金属矿矿床模式和"瑶岗仙式"石英脉型钨锡矿矿床模式。在上堡地区的找矿过程中,运用预先建立的矿床模式对石枕头铅锌矿、田木冲钨锡多金属矿和刘家锑铅多金属矿等矿床(点)的找矿工作进行指导,并通过具体的找矿实践,不断检验和修正矿床模式,使之更符合本区的实际情况,收到了比较好的找矿效果。The Shangbao area of Hunan is an important part of Nanling metallogenic belt which is located in the west section of Nanling metallogenic belt, with an area of about 2700km2. In this region, Tashan rock mass, Dayishan rock and upper rock body together constitute the Tashan- Dayishan- Shangbao east-west tectonic-magmatic belt. Considering about ore-forming geological conditions and features of known deposits in the working area, huangshaping type Pb- Zn- Ag-Cu skam depositmodel, shizhuyuan type W-Sn polymetallic skam deposit model and yaogangxian type quartz vein W-Sn deposit model are established in advance. In the process of prospecting in the shangbao area, the good orc-prospecting effects are received by using the pre-established deposit model to guide the prospecting work of Stonepillow Lead ＆ Zinc mine, Tianmuchong W-Sn polymetallic ore and Liujia Sb-Pb polymetallic deposit, and constantly testing and fixing deposit model to make it much more in accordance with the actual situation of this area through specific prospecting practice.
