摘　　要：石庄下铅锌银多金属矿位于甘肃省天水市麦积区,地质特征独特且具有较高的找矿潜力。该矿床赋矿地层为中下元古界秦岭岩群、上泥盆统大草滩组,侵入的岩株和岩脉为铅锌银等元素的富集提供了物质来源。同时,区内次级断裂改造地层和岩体结构,为成矿物质运移提供通道。综合分析认为,石庄下铅锌银多金属矿具备寻找岩浆期后热液有关的构造角砾岩型矿产的条件。进一步勘查工作将有助于揭示矿床的位置、规模和成因类型,为未来的开发利用提供重要参考。The Shizhuangxia lead-zinc silver polymetallic deposit is located in Maiji District,Tianshui City,Gansu Province,with unique geological features and high prospecting potential.The ore bearing strata of this deposit are the Qinling Formation of the Middle Lower Proterozoic and the Dacaotan Formation of the Upper Devonian.The intrusive rocks and veins provide material sources for the enrichment of elements such as lead,zinc,and silver.At the same time,secondary faults in the area transform the geological and rock structures,providing pathways for the migration of ore-forming materials.Comprehensive analysis suggests that the Shizhuangxia lead-zinc silver polymetallic deposit has the conditions to search for structural breccia type minerals related to post magmatic hydrothermal conditions.Further exploration work will help reveal the location,scale,and genetic type of the deposit,providing important references for future development and utilization.
