摘　　要：在系统总结白云铺铅锌金矿床成矿地质背景、矿床地质特征的基础上,通过分析湖南新邵白云铺矿区矿石铅、硫、氧同位素特征以及流体成分特征、成矿温度等,结合区域内大中型铅锌、金矿床的研究成果,从矿质来源、成矿流体来源、成矿作用等方面探讨了本矿区铅锌矿和金矿的矿床成因类型,并建立了成矿模式。研究认为,白云铺铅锌矿床为地台阶段形成的同生沉积改造层控型铅锌矿床,白云铺金矿为中低温热液蚀变岩型金矿床。研究成果可为该区的找矿勘探及成矿作用研究提供参考。On the basis of systematical summary of the metallogenic geological background and geological characteristics of Baiyunpu Pb-Zn-Au deposit,through analysis of the ore lead,sulfur and oxygen isotope characteristics,fluid composition characteristics and metallogenic temperature,combined with the research result of large and medium scale lead-zinc and gold deposits in the region,the genetic types of lead-zinc and gold deposits in this mining area are discussed from the aspects of mineral sources,ore-forming fluid sources and mineralization function,and the metallogenic model is also established.It is considered that Baiyunpu lead-zinc deposit is a syngenetic sedimentary reformed stratabound lead-zinc deposit formed in the platform stage,and Baiyunpu gold deposit is a medium-low temperature hydrothermal altered rock type gold deposit.The research result can provide a reference for prospecting work and mineralization study in this area.
