In What Rock Formations Can Gold Be Found? Sciencing

24/04/2017  Intrusive rock is formed when molten magma is pushed between layers of existing rock. Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.
