The concept of minerogenetic series of mineral deposits (called metallogenic series for short) is not only a kind of academic thought of regional metallogenic research, but also a four- dimensional metallogenic theory of earth system. It considers that the earths world of mineral deposits is composed of natural body of mineral deposit type association- minerogenetic series for mineral deposits andits consortium formed by various types of geological mineralization in a specific time domain and a specific space domain. The mineral deposit formation is controlled by three ore- forming elements of time, space and mineralization. The basic unit of the mineral deposits world is the minerogenetic series for mineral deposits. The metallogenic series for mineral deposits constitute the metallogenic system, and the metallogenic system constitutes the mineral deposits world. Six orders of metallogenic series are proposed in this paper.
