摘　　要：本文详细论述水埠头锰矿床的地质特征,分析控矿因素及地球化学特征,提出成矿环境。水埠头锰矿主元素、微量元素的组成具有深源和陆源的双重特征,表明其物质来源是多源的。微量元素及岩相古地理特征提示其形成的物理化学条件为:水动力条件微弱的以弱氧化—缺氧为主的环境;Fe-Mn-(Ni+Co+Cu)×10的关系说明,矿床属热水沉积成因。This paper discusses in detail the geological characteristics of Shuibutou manganese deposit, analyzes geochemical characteristics and ore-controlling factors, presents metallogenic environment. Shuibutou manganese deposit major and trace element composition with a double feature deep and land-based sources, indicating that material source of manganese is polygenetic. Features of trace elements and lithofacies paleogeography suggest that physicochemical condition of metallization:hydrodynamic conditions weak dysoxic-anoxic environment dominated. Relations Fe-Mn-(Ni+Co+Cu)×10 indicates that deposit genesis is hydrothermal sedimentary.
