This paper presents the advances and trends of the research into tectonics_fluids_mineralization system and dynamics. On this basis, this paper tentatively proposes the theoretical framework and methodological system of the tectonics_fluids_mineralization system and dynamics. The tectonics_fluids_mineralization system is defined as an entity comprising of all geological factors and processes controlling and transforming the formation and preservation of ore deposits and their products. With tectonics_fluids playing a leading role, this system is also defined as a complex dynamic system occurring in a certain spatial_temporal zone and consisting of the coupling and telescoping of components and processes. The corresponding dynamics is defined here as the dynamic system/mechanism of mineralization system settings, mineralization system itself and ore_forming materials. This system includes the kinetic and geometric features of ore_forming structures, fluids and materials, and the differences between ore_forming process, potential to accumulate ore_forming materials and ore_forming products. This system highlights the importance of tectonics and fluids in the ore_forming process and stresses the entity and comprehensive effects initiated by the coupling and telescoping of components and processes. In this sense, this paper points out that the tectonics_fluids_mineralization system is characterized by gradation_entity, complexity, self_organizing criticality, network, orientation and optimum structure with the gradation_entity the most important feature. Guided by the theory about this system, the authors of the present paper propose that the tectonics_fluids_mineralization system and its dynamics should be viewed as a whole body and the formation process and dynamic feature of the tectonics_fluids_mineralization system should be under investigation in terms of the interaction between fluids and petrology_tectonic environment and also of the evolution of the tectonics_fluids. Following the principle of practice-recognition-re_practice-re_recognition and guided by the macroscopic theory of entity based on the multi_discipline researches, this paper presents the deep analysis of the principle of the spatial_temporal trace of a typical mineralization system that was viewed between the microscopic and macroscopic extremes. The principle thus concluded can be used to guide the research into the microscopic mineralization process and mechanism, to actualize the system, entity, and quantification of the present research, and to understand within a wider range and a deeper layer the spatial_temporal structure and nature of the tectonics_fluids_mineralization system.
