摘　　要：本文以贵州省印江县梵净山石柱岩铜砷矿床勘探地质成果资料①为依据,论述了矿床地质背景、矿床地质特征及控矿因素,并在此基础上阐明了成矿物质来源于该矿床附近的花岗岩。石柱岩铜砷矿的赋存与富集严格受花岗岩、辉绿岩、断层破碎带及硅化围岩蚀变的多重控制,含矿热液沿断层破碎带活化迁移,富集成矿。矿床成因类型为岩浆期后中温热液型铜砷矿床,其成矿时代归属武陵期。According to the geologic results and information of deposit exploration of Shizhuyan copper and arsenic deposit in Yinjiang,Guizhou,it analysis the geologic background,geologic character and ore control factors of the deposit,and then explains that the mineral material come from the granite nearby.The occurence and concentration of Shizhuyan copper and arsenic deposit is controlled by granite,diabase,fault cracking zone and silicified wall rock alteration,the ore bearing hydrothermal solution activation migrates along the cracking zone.The genetic type of mineral deposit is post-magma mesothermal deposit.
