摘　　要：用非线性科学和复杂性理论对湖南郴州柿竹园超大型钨多金属矿床的成矿复杂性进行系统、深入的研究 ,以成矿作用与时空结构是一切矿产资源的本质与核心的自然哲学理念为根本立足点 ,从一种新的视角 ,就矿床的动力学属性、矿床的物质成分与结构、矿床的地质学场和成矿系统的演化四大相互联系的范畴 ,对矿产资源进行再认识 ,提出了矿床的新定义 ,并较深刻地揭示了矿床的动力学属性、成矿物质高度多样化和复杂性及其超常规模集成、矿田成矿分带的内部结构、矿床地质学场的时空分形结构、成矿系统时间演化的长期性和成矿过程的多期多阶段性以及成矿作用的发生和矿床形成的分形生长机制等方面的复杂性与动力学本质。项目成果将矿床学的研究提高到非线性科学和复杂性理论的层次 ,提供了如何应用这种理论和方法对矿床的成矿复杂性进行研究的实例 ,也是第一作者所提出的关于成矿系统复杂性的新成矿理论与方法论“成矿动力系统在混沌边缘分形生长”的具体化及其进一步深化。沿着这一研究方向的不断开拓将可使传统矿床学向精确科学跨越。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.
