Slide 4: Epithermal Gold Systems
Epithermal Gold Systems • Formed in active volcanic regions • Essentially fossilized geothermal cells • Hot fluid following fractures and faults exits at surface as geysers and hot springs • Gold-silver deposited with and in quartz veins at specific temperature/pressure • Epithermal systems develop
