| 摘 要： | 分析了热液成矿作用的基本特点和研究现状，推导出热液成矿作用动力学体系的一般方程，并着重讨论了方程中表征热液与围岩之间化学反应的速率项，除目前一般采用动力学实验实测反应速率常数外，作者根据局域平衡原理，认为成矿作用可视为体系内各点随着温度和压力的变化不断重建平衡的过程，可用温度和压力变化时成矿反应的平衡常数的变化速度表征成矿反应的动力学行为，成矿化学反应的速率还可用主要成矿物质的溶解的变化率来表征。

| Abstract: | The paper provides an insight into the basic characteristics and recent status of investigation of hydrothermal ore -forming processes. A group of universal equations describing the processes are then deduced. Special emphasis is placed on how to express the rate of the different types of reaction between surrounding rocks and ore-forming fluids. In addition to measuring the rate by dynamic experiments, the authors propose to use the changing rate of re-action's equilibrium constant with temperature and pressure according to local equilibrium thoery or to apply dissolution rate in investigating the dynamic behavior of hydrothermal ore -forming processes. The correspondent rate formulae are provided to construct a complete system of the processes. |
