Wisconsin Geological Natural History Survey Gold

It may also form in veins formed along major fault zones. Gold in veins is associated with sulfides, quartz, and calcite. Gold is resistant to weathering, hence is often freed from the surrounding rock and redeposited as sediment. Because gold has a high density, it tends to settle out readily and be trapped with coarser sediments.
