本文首次对黔西南和桂西北微细浸染型金矿床围岩、矿石和热液硅化石英的硅同位素组成结合硅质阴极发光特征进行了研究，发现原生硅化石英不发光，而围岩中的石英和次生硅化石英明显发光；与此对应，围岩与矿石和热液硅化石英的硅同位素组成也可以明显分开，并从硅同位素动力学分馏原理分析论证了原生成矿硅质流体在沿深大断裂主通道由深至浅快速运移时，沿途进入次级断裂分别向不同的有利于赋矿的地层渗透交代而成矿的地球化学过程。由此为该类型金矿的成矿物质主要来源于深部提供了重要依据，揭示了该类型金矿具深部找矿远景及形成大型和超大型矿床的地球化学背影。
This paper, for the first time, studied the siliceous cathodoluminescence characteristics of the siliceous cathodes of the surrounding rocks, ore and hydrothermal silicified quartz in the finely disseminated gold deposits in the southwestern and western Guangxi and found that the native silicified quartz did not emit light, whereas the quartz and Corresponding to this, the silicon isotope composition of the surrounding rock and ore and the hydrothermal silicified quartz can also be clearly separated. From the analysis of the principle of silicon isotope dynamic fractionation, it is demonstrated that the primary mineralized siliceous fluid is deep along the deep When the main channel of fault fractured from deep to shallow, it migrated into the subfacies along the way and infiltrated into different ore-benefiting strata infilling and metasomatism respectively. Therefore, the ore-forming materials of this type of gold mine mainly come from the deep to provide an important basis, revealing the type of gold prospecting with deep prospect and the formation of large and super-large deposits of geochemical backs.
