摘　　要：以湘西花垣县大脑坡矿区作为研究对象,在前人研究的基础上,通过野外地质勘查工作,综合研究分析及对比前人的成果,首先介绍了矿区地层、构造、岩相特征、控矿因素等内容,大致分析矿区的成矿地质条件,重点讨论了藻礁对铅锌矿富集及成矿的影响。相较于其他沉积型铅锌矿床,大脑坡铅锌矿床受海藻生物的影响更大,其生长聚集形成的藻孔为铅锌矿提供了重要的容矿空间。With the mining area of Danaopo in Huayuan County,Xiangxi,as the research object,based on previous studies and through field geological exploration,comprehensive research,analysis,and comparison of previous achievements,this paper first introduces the strata,structure,lithofacies characteristics,ore-controlling factors,etc.of the mining area,roughly analyzes the metallogenic geological conditions of the mining area,and focuses on discussing the influence of algal reefs on the enrichment and mineralization of lead-zinc deposits.Compared with other sedimentary lead-zinc deposits,the Danaopo lead-zinc deposit is more affected by seaweed organisms,and the algal pores formed by their growth and aggregation provide important ore-hosting space for lead-zinc deposits.
