金矿床中硅质流体侵位方式及演化与成矿关系

The relation of emplacemental fashion as well as evolution of the silicic fluid and formating deposit

根据对形成石英脉的硅质流体在导矿构造和容矿构造中与围岩的作用方式分析,将硅质流体的侵位方式分为主动侵位和被动侵位,并结合莫尔圆理论论述了其实现的可能性。同时根据不同侵位方式的硅质流体与围岩发生水-岩交换程度的不同,论述和分析了硅质流体侵位方式及演化与成矿的关系。最终,形成和建立了硅质流体的侵位方式及演化与成矿模式,初步讨论了影响硅质流体侵位方式的因素。

According to the analysis of interaction way between the silicic fluid to form quartz vein and the enclosing rock in the passable structure or in the host structure, the emplacemental fashion of the silicic fluid is divided into the active and the passive emplacement. And the possibility of realizeing them are discussed by means of the theory of Mohr. On the basis of the different extent of water-rock replacement between the enclosing rock and the different way emplacemental silicic fluid, the relation of the emplacement fashion as wellas evolution of the silicic fluid and the forming ore is discussed and analyzed. Then, the pattern of the emplacement fashion as well as evolution of the silicic fluid and the forming ore is constructed. The possible factors of affecting the emplacement fashion are discussed.
