| 摘 要： | 热液成矿分带是普遍存在的规律。在研究银山和铜厂等具体矿床分带规律的基础上,总结出热液成矿分带具有径向对称性,并且用自孤子理论研究了其内在机制,指出热液矿床是活性扩散系统中的自孤子,给出了热液成矿自孤子的定义。用静态径向对称自孤子模型对热液成矿分带的径向对称性进行了描述和分析,得出了一些定性的认识,它们对更深入地研究热液成矿分带的动力学机制和成矿地球化学过程具有一定的意义。

| Abstract: | Hydrothermal ore zoning is commonly observed. We proposed that hydrothermal ore zoning is radially symmetric after having investigated mineral deposits such as Yinshan and Tongchang. We studied its mechanisms qualitatively by the application of the theory of autosoliton, pointed out that hydrothermal deposits are autosolitons in active systems with diffusion, and defined hydrothermal ore forming autosoliton. We described the radially symmetric structures of hydrothermal ore zoning by static radially symmetric autosoliton model. Several theoretical conclusions were obtained, which we thought are important in deep research on the dynamic mechanisms and geochemical processes of hydrothermal ore zoning. |
