Abstract：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.
