剪切带构造成矿动力机制与模式

动力学是确定系统演化和最终结果的关键，系统动力学是了解复杂系统的一种构模方法，主要用于处理关于系统行为随时间变化的问题。剪切带构造成矿系统动力学主要指剪切带构造动力对成矿系统过程的启动、运行机制，以及成矿物质的运动学、几何学特征的控制以及由此产生的成矿过程、聚矿能力和成矿产物之差异。文章着重从剪切带构造成矿动力机制和模式等方面进行阐释，强调构造和流体对成矿的重要性，阐述了“断裂阀地震泵吸周期性破裂愈合”的构造流体耦合成矿动力机制，提出了动力系统分析模式并综合了数值分析模式，明确指出成矿系统动力学计算机模拟是动力系统分析和数值分析有机结合的产物，是定性综合与定量分析的统一，是成矿系统动力学研究的发展方向。

DYNAMIC MACHANISM AND MODEL OF ORE FORMING SYSTEM OF SHEAR ZONE TECTONICS

Dynamics of system is one way to construct model which displays the complexity of system. It mainly deals with these questions relating to behaviors of system which change with time. Ore forming system is a super complex entirety and is made up of multi lever time scale, manifold ore controlling parameters and multifarious processes. Ore forming processes are complex non linear dynamic processes. Dynamics is the key to define the evolution and final outcome of the system. Dynamics of ore forming system of shear zone tectonics contains the machanism of how the dynamic of the system of ductile brittle shearing start and continue the processes of the system, and the characters of kinematics and geometry of ore forming materials and the differences of ore forming processes, capacity and outcome caused by them. The authors emphatically expound the dynamics of the system's evolution, machanism, model and simulation, and emphasis the importance of tectonics and fluid. The computer simulation of dynamics of ore forming systems is the combination of dynamic system analysis with numerical analysis and is the enterity of quantitative analysis and qualititative synthesis. In the paper, the authors expound the concrete methods and the theoratical and practical significance of researches of dynamics of ore forming systems of shear zone.
