Electron microscope (EM)and energy dispersive spectrometer (EDS) were used to detect the composition of the Au-bearing quartz, the ion diffusion and the occurence states of gold. Their mechanism of formation and variation were discussed.

• 利用电子显微镜(EM)及能谱仪(EDS),分析研究了变生热液形成的载金石英的化学成分、离子扩散作用以及金在石英中的赋存状态等问题,探讨了它们的形成和变化机理。
