摘　　要：土地庙沟铅锌矿区位于土地庙沟—维摩寺铅锌银多金属成矿带中,是豫西南铅锌银多金属成矿区的重要组成部分。文章通过野外地质特征、岩相学及地球化学研究分析,认为煤窑沟组为区内主要赋矿层位,NWW-NW向断裂为该区的主要控矿构造,燕山期复式岩体与成矿关系密切,成矿物质主要来源于岩浆,但有地层物质的混入,矿床成因属于与燕山期岩浆活动有关的热液型铅锌矿床。The Tudimiaogou Pb-Zn deposit located in the Tudimiaogou-Weimosi lead -zinc-silver polymetallic metallogenic belt, is an important part of Yuxina lead-zinc-silver polymetallic metallogenic province. Based on the field geological investigation, petrographic study and geochemical analysis, it is concluded that the Meiyaogou group is the main ore-bearing layer, NW-trending and NWW-trending fractures are the main ore-controlling structures, and there is a close relationship between mineralization and Yans- hanian complex rock mass. Ore-forming materials mainly derived from magma mixed with strata material. The deposit genesis belongs to hypabyssal hydrothermal Pb-Zn deposit related to Yanshanian magmatic activity.
