摘　　要：贵州二叠系锰矿主要以碳酸锰和氧化锰矿石为主,主要分布于遵义—黔西—纳雍—水城一带的台沟相内,对其形成时代一直以来都有争议。笔者通过对该区锰矿沉积特征及其与峨眉山玄武岩的接触关系等来探讨贵州二叠系锰矿成矿时代,认为贵州二叠系锰矿成矿时代属于中二叠世茅口晚期。The Permian manganese of Guizhou is mainly carbonate manganese ore and oxide manganese ore,which mainly distributes within the platform and trench facial zone of Zunyi-Qianxi-Nayong-Shuicheng.Its mineralization age has always been a controversy.It is proposed that mineralization age of Permian Manganese of Guizhou is the upper MaoKou Formation of Middle Permian on the basis of its sedimentary characteristics in the area and contact with the Emeishan basalt.
