Abstract: The comprehensive analysis of advances in the research into the ore forming dynamics concludes in this paper that the research into the ore forming dynamics of the tectonic regime transformation and multi layer circulation is on the cutting edge of the earth sciences in the 21st century. Then the paper presents the theme, key issues, methodology, and important significance of this research. In addition, this paper also proposes that the research into the ore forming dynamics of the tectonic regime transformation and the multi layer fluid circulation centers around the heterogeneities in the structural evolution, fluid activity, regional geochemistry and geophysics. The experiments on the deformation fluid high temperature and high pressure, the method for numerical simulation to reappear the ore forming process and mechanism, to analyze the ore forming dynamics of the tectonic regime transformation and multi layer fluid circulation, to reveal tempo spatial evolutionary patterns of the ore forming interfaces, and finally to construct the quantitative model of the exchange between material and energy feedback coupling mineralization in the mineralization system. This research, an important basis of the deeper understanding of the mineralization origin, and an effective approach to the scientific mineral prospecting, is of great significance to the research into the earth system science and continental dynamics.
