摘　　要：板块构造与全球大型 超大型金矿分布间的内在联系一直被世人所关注。本文根据板块体转动引起岩石剩磁矢量方向的变化 (由原正 负磁极相对变为正 正极或负 负极相对 )所产生的磁斥力以及磁斥力对金元素运移和富集的控制作用 ,探求磁斥力的形成特征与全球金矿分布规律的对应关系。基于磁力控矿理论基础、磁斥力形成和控矿机制及全球大型 超大型金矿分布规律的讨论 ,提出全球大型 超大型金矿床的形成 ,除有区域构造应力和重力等作用外 ,还应与磁斥力作用有关。磁斥力值、板块体旋转角度及金矿床的形成 3者间具有一定的对应性 ,磁斥力大小与金矿床形成规模成正比。这种正比关系决定了全球大型 超大型金矿床空间展布主要呈环形、对顶角式和等距性分布 。The Internal relation between plate tectonics and distribution of global large/super large gold deposits has been arousing a hot spot concerned by the world people. On the basis of plate rotating bringing change of rock remanent vector, magnetic repulsive force forming and magnetic repulsive force controlling gold element motion and enrichment, the paper tried to search a corresponding relation between magnetic repulsive force forming and distributive law of global gold deposits. In allusion to discussing of magnetic force controlling deposits theory, magnetic repulsive force forming, controlling deposits mechanism and distributive law of global large/ super large gold deposits, our work indicated the follows. 1) Magnetic repulsive force played an important role in forming of global large/super large gold deposits, in addition to tectonic force and gravity. 2)There was a definite corresponding among magnetic repulsive force value, plate rotating angle and gold deposits, namely, magnetic repulsive force was directly proportional to scale of gold deposits. 3)The relation of direct proportion decided that the space distribution of global large/super large gold deposits taking three forms: ring, vertical angle and isometry, which reflected general tendency of global metallogenic evolution.
