The metallogeny put forward in this paper is the summary report of systematic researches carried out by the author for several decades on basic paradigms of six metallogenic districts at the Yangtze Cratonic Rim by combining the theory of Complexity and science of nonlinearity with ore geology. Invesitgation shows that the ore forming systems are open, far from equilibrium and spatio temporally extended dynamic systems. They possess the inherent fundamental attributes of complexity and self organized criticality, and grow fractally at the edge of chaos. The author takes the natural philosophical reasoning of 'geological processes and spatio temporal structures are the essense and crux of geological phenomena'as the fundamental foothold, and sets up an universal framework for the theory. Then it is realized and specified by three major constituent parts, i.e . dynamic attributes of ore deposits fields of ore geology evolution of ore forming systems. They embody the integral coupling and intermingling of the trinity of the ore forming processes (the core of which is the dynamics of ore forming processes) the spatial structures (fields of ore geology) temporal structures (evolution of ore forming systems). Thereby the metallogeny is endowed with comprehensiveness. Furthermore, five determinative criteria for the 'Fractal growth of ore forming dynamical systems at the edge of chaos'and ten corresponding characteristics of dynamic behavior are derived on this basis. The theoretical and logical interrelationships among the theoretical framework determinative criteria characteristics of dynamic behavior constitute the methodology of holism for global research of the metallogeny. In addition, the reductionism is taken as a subsidiary methodology for further study. It takes the dynamic mechanism of the balancing between local activation and long range inhibition of autosolitons as the core of ore formation, use the 'cell nonlinear networks'(CNN) as paradigms of complexity for quantitative identification and localization of local activity.
