The authors applied the science of nonlinearity and the theory of complexity to studying systematically and profoundly the complexity of ore formation for the super-large tungsten-polymetallic ore deposit of Shizhuyuan, Hunan Province in China. They take the natural philosophical reasoning of 'ore-forming processes and spatio-temporal structures are the essence and crux of mineral resources' as the fundamental foothold to recognize mineral resources from a new viewpoint in connection with the four major interrelated categories-the dynamical attributes of ore deposits, the composition and structure of ore deposits, the geological field of ore deposits and the evolution of ore-forming systems. The authors put forward a new definition for ore deposits, and reveal profoundly the complexity and the dynamical essence of: (1) the dynamical attributes of ore deposits, (2) the extreme diversity and complexity of the ore-forming materials and their aggregation with extraordinary scale, (3) the internal structure of ore zoning of the ore field, (4) the spatio-temporal fractal structure of the geological field of the ore deposits, (5) the long-term nature of the temporal evolution of the ore-forming system and the multiplicity of periods and stages of the ore-forming processes, and (6) the onset of ore formation and the mechanism of fractal growth of ore deposits. The research raises the study of ore geology to the level of the science of nonlinearity and the theory of complexity, and provides a case study for investigating the complexity of ore formation with the theory of complexity. It is also the concretion and the further deepening of the new metallogeny and methodology 'Fractal growth of ore-forming dynamical systems at the edge of chaos' advanced by the first author. By sustainedly developing and deepening along this direction of investigation, it would be expectable to realize the crossover of the traditional ore geology to the exact sciences.
