| 中文摘要:基于成矿“时间维”造就“空间维”的活动论新思维，提出了金属成矿省 等级体制成矿概念，即成矿构造背“景”、成矿构造聚敛“场”、金属成矿“相”和矿“床 ”4个成矿等级在1个金属成矿省内的成矿作用，及其随着地质历史演化进程，通过在一定地 质时期的一定地质事件，促发4个不同等级的成矿组成以一定规律发生耦合。不耦合者不成 矿，一般耦合仅成一般规模矿床，最佳耦合导致巨量金属堆积，形成特大型矿床。文章以华 北板块北缘及其北侧金属成矿省为例，通过成矿等级体制的有序耦合、耦合程度及其巨量金 属堆积机制的研究，发现巨量金属的堆积是在一定的地质历史时期内，由一定的地质事件激 发常规成矿作用发生异常“引潮共振”的结果。 |

| Abstract:Based on the metallogenic mobilistic thought that time_dimension generates space _dimension, the authors put forward the theory of hierarchy systematic metalloge ny of a metallogenetic province. It is considered that tectonic setting, metallo tect convergence, metallogenic phases and ore deposits consist of the metallogen ic hierarchy system of a metallogenic province and that the formation of ore dep osits is based on their catenation conforming with some geological evolution reg ularities. Hierarchy systematic metallogeny is exemplified mainly by the metallo genic province of North China Platform and its northern side. The relationship b etween the catenation degree of the metallogenic hierarchy system and the accumu lation of metals or super_accumulation of metals suggests that no catenation of the four classes results in no ore formation, general catenation leads to the fo rmation of small to middle deposits, and best or optimum catenation forms giant ore deposits induced by super_accumulation of metals. It is considered that the super_accumulation of metals is induced by the explosion of exceptional ore_form ing process in some epochs of geological history. |
