Gold is typically concentrated in quartz veins, where it precipitates from hydrothermal fluids under specific pressure and temperature conditions. These veins are formed over millions of years and ...

Structures? Check. The rocks of this area also have a profusion of hydrothermal alteration assemblages, with spectacular, bright green epidote, massive patches of garnet, and intricately deformed, ...

New Epithermal Gold System: an extensive network of quartz veins is hosted in hydrothermal breccias with associated high temperature alteration - characteristic of epithermal gold deposits.
