| 摘 要： | 热液成矿分带是一种输运－反应问题。热液成矿分带基本属于渗滤交代分带性质，它是溶解－沉淀波在可渗透介质中形成和传播的结果。本文应用物理化学流体动力学中的渗滤与溶解－沉淀反应耦合过程理论研究溶解－沉淀波的结构特征，并进一步应用多组分耦合系统动力学中的用于原理揭示其形成的动力学机制，最后提出了一种热流成矿分带理论，对热液成矿分带问题的性质、热液成矿分带的本质和热液成矿分带的结构特征与形成机制提出了新认识。

| Abstract: | Hydrothermal ore zoning is a transport-reaction problem in which infiltration is the principal process of transport and dissolution/precipitation is the principal process of chemical reactions .Neglecting diffusion and ion exchange/adsorption would not affect the basic attributes of hydrothermal ore zoning. Hydrothermal ore zoning belongs essentially to infiltration metasomatic zoning ,it results from the formation and propagation of dissolution/precipitation waves through permeable media.The authors apply the theory of coupled infiltration and dissolution/precipitation reactions in physicochemicalhydrodynamics to studying the structural characteristics of dissolution/precipitation waves,and applyfurthermore the coherence principle in dynamic theory of multicomponent coupled systems to revealing the dynamic mechanisms of their formation .The results of investigation verify and develop C.theory of infiltration metasomatic zoning ,on the one hand ,raising it from the pualitative ,equilibrium thermodynamic basis to the puantitative dynamic level;on the other hand ,and more importantly ,applying theories of physicochemical hydrodynamics and dynamics of multicomponent coupled systems to bringing to light the dynamic mechanisms of formation of the structure of hydrothermal ore zoning,and advancing a theory of hydrothermal ore zoning ,putting forward new ideas on the nature of the problemof hydrothermal ore zoning ,the essence of hydrothermal ore zoning and the structural characteristics and mechanisms of formation of hydrothermal ore zoning . |
