How Is Gold Formed and Where Does it Come From?

At different times in the earth’s history, hot fluids circulated through gold-bearing rocks and because of the weight and chemical properties of the gold, the gold may have been carried off to form a vein or a lode. In other instances, gold flakes and nuggets broke off and were carried away by water’s currents.Gold Prospecting | How to Find Gold in the United StatesHydrogeochemical prospecting for gold: Groundwater collected from wells, springs, and drill holes may provide clues to the presence of subsurface gold deposits. As groundwater flows through the deposit, minute amounts of gold are leached from the rocks. These can sometimes be detected in groundwater samples collected from wells located down gradient from the deposit.
