Abstract: In the course of exploring metallogenic regularities and prospecting deposits, a concept Metallogenic System was proposed through studying magmatic hydrothermal mineralization, metallogenic structural system and metallogenic series, etc. This concept has been endowed with different definitions and used for prospecting practice, and a large amount of achievement has been made. But there has been less investigation on when, where and how the metallogenic system started, resulting in existence of some controversies. This paper proposed a new concept of metallogenic system based on studying and summarizing magmatic hydrothermal mineralization to magmatic hydrothermal metallogenic system, metallogenic structural system to metallogenic system and mineralization series. The definition for the metallogenic system reveals its new features. Finally, this study also made prediction for mineralization, assessed potential of mineral resources, and summaried the latest results and new progress, based on faulting network-metallogenic system, metallogenic structure system, and metallogenic system absence. Therefore, this study will have some reference for future study of mineral exploration.
