中文摘要:在成矿过程中，普遍存在成矿参数的临界转换现象。在制约成矿临界转换的参数和多种形式中，构造动力转换可能起着根本的作用。文章以山东焦家、阜山等矿床为例，列举剪切带构造中的临界转换现象。又以火山爆发和地震为例，说明构造动力体制转换诱发的突发地质事件及伴随的成矿作用。在说明构造动力转换的多重尺度后，重点论述了整体构造背景下的局部转换（例如总体挤压背景下的局部拉张、总体拉张盆地中的局部封闭）是一常见的矿源-运输-汇聚结构。在构造动力体制转换带动下，多种参数的联动转换是形成大型矿床的一种机制。
Abstract:Critical transition of ore-forming parameters is one of the main topics in the metallogenic researches. Among the parameters that control the ore-forming critical transition, tectonic dynamic transformation see ms to play the most important role. Taking the Jiaojia and the Fushan gold ore deposits as examples, this paper enumerates some critical transforming phenomena in gold- bearing shear zones, and also exemplifies incident geological events and accompanying mineralization induced by the transition of tectonic dynamic mechanism through volcanic explosion and earthquake. Following an illustration of the multi-scale nature of tectonic dynamic transition, this paper stresses that local transition under a certain tectonic setting is a common ore source- transportation-enrichment structure (e.g. local extension under compressional tectonic setting , local closing in an extensional basin). Coupling transitions of many ore-forming parameters induced by the tectonic dynamic transition is one of the mechanisms forming large-size ore deposits.
