This paper briefly introduces the state of gold in quartz and its migration pattern. The electronic structure and properties of gold, the electronic structure of silica and the surface characteristics of quartz crystal are discussed. The 18-electron rule and crystal of stable complex Growth interface phase model to analyze and understand the gold-bearing mechanism of quartz. After analyzing and studying, it is considered that the gold content in quartz is not only related to the surface structure, internal defects and surface features of quartz, but also to the environment in which quartz is grown. In particular, it is related to the surface electronic bond structure of quartz and is mainly affected by the growth of quartz crystal In the search for quartz vein type gold deposits and study of the mechanism of quartz gold, we should not only pay attention to the characteristics of ore-forming fluid, but also pay more attention to the interface phase of quartz crystal growth.
