成矿动力系统在混沌边缘分形生长——一种新的成矿理论与方法论(下)

FRACTAL GROWTH OF ORE-FORMING DYNAMICAL SYSTEMS AT THE EDGE OF CHAOSA NEW METALLOGENY AND METHODOLOGY (Second half)

:“成矿动力系统在混沌边缘分形生长”理论是笔者将复杂性理论及非线性科学与矿床地质学相结合 ,对中国扬子古陆周缘六个矿集区的基本范式进行长期系统研究所取得的总结性成果。研究指出 ,成矿系统总体上是开放、远离平衡、时空延展的动力学系统。它们具有复杂性和自组织临界性的内禀基本属性 ,并且在混沌边缘分形生长。该理论以“地质作用与时 空结构是一切地质现象的本质与核心”的自然哲学理念作为根本立足点 ,建立起一种具有普适性的理论框架。然后进一步将其具体化为三大组成部分 ,即 ( 1)矿床的动力学属性 ,( 2 )矿床地质学场 ,( 3 )成矿系统的演化。体现了成矿作用 (其核心为成矿作用动力学 ) ,空间结构 (矿床地质学场 )和时间结构 (成矿系统的演化 )三位一体的整体耦合与交织 ,从而又使该理论具有包容性。在此基础上进而归纳出“成矿动力系统在混沌边缘分形生长”的 5项判定准则以及表征这些准则的 10项相应的动力学行为特征。最后笔者提出“矿质局部活化导致成矿的发生”的命题 ,拟定了“成矿的发生”的重要科学问题 ,以“元胞非线性网络”(CNN)作为复杂性的范式 ,定量揭示成矿的发生 ,并对矿床在混沌边缘作精确定位 ,对“成矿动力系统在混沌边缘”理论作进一步的延伸、深化与发展。该理论在?

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. Investigation shows that the ore forming systems are open, far from equilibrium and spatio temporally extended dynamical 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 essence and crux of geological phenomena' as the fundamental foothold, and sets up a universal framework for the theory. Then it is realized and specified by three major constituent parts, i. e. (1)dynamical attributes of ore deposits,(2)fields of ore geology and (3) 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) and 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 dynamical behavior are derived on this basis. Finally, the author advances the proposition of 'the local activation of ore\|forming materials induces the onset of ore formation', poses its four important scientific problems, and takes 'cellular nonlinear networks' (CNN) as paradigms of complexity to reveal quantitively the onset of ore formation, and to localize precisely ore deposits at the edge of chaos. The new metallogeny would thereby be extended, deepened and developed.The new metallogeny raises the conventional ore geology to the level of the science of nonlinearity and complexity with respect to the study of ore genesis and regularity of ore formation.
