摘 要:含金建造是富含C、S、Fe的沉积岩系或火山沉积岩系,根据形成环境和演化特点,将含金建造划分5种类型.认为金元素地球化学二重性决定其成矿作用具有二重性,含金建造是各种类型内生金矿床成矿物质的直接来源,成矿热液来源于建造水.对独立金矿床进行了类型划分,强调含金建造的存在是金矿成矿的基本条件,运用液态矿源说和二次迁移论探讨了成矿作用机制,并建立了金矿成矿模式.Auriferous formations, which are made of sedimentary rocks or volcanic sedimentary rocks containing C, S and Fe, can be divided into five types depending on their forming conditions and evolution. The dual nature of Au element determines its characteristics of dual mineralization process. Metallogenetic materials of all endogenetic gold deposits come directly from auriferous formations. The metallogenetic hydrothermal fluids are evolved from water in the auriferous formations. Absolute gold deposits are classified as six types, based on auriferous formations that are the foundation of Au mineralization. The mineralization mechanism of gold deposits is discussed referring “liquid state ore source' and “secondary transportation'. The metallogenetic model of gold deposit is set up.
