MECHANISM OF GOLD OCCURRENCE IN PYRITE AND QUARTZ CRYSTALS

On basis of electron structure and property of gold, characteristics of pyrite crystal structure, electron structure and characteristics of silica and surface feature of quartz crystal mechanism of gold occurrence in pyrite and quartz is discussed. Au + and Au - ion replace Fe 2+ and S 2- and vissible gold can be formed in pyrite. Gold concentration in pyrite is mainly related to the pyrite crystal structure, especially to F S,S S,Au S and Fe Au bonds. According to 18 electron regulation about assorting meterial and the interface phase model of crystal growth gold occurrence in quartz crystal is not only related to surface structure, inner defect of quartz crystal grouth but also to the quartz crystal growth environment, especially to electron structure of surface bonds of quartz crystal. Trap of gold in quartz is maily controled by interface phase during growth.
