· Alluvial gold is gold that has been freed from its host rock and ended up where it is after having been moved by water. Examples would include modern river and creek gravels, fossil tertiary river beds and terraces, as well as modern and ancient beach deposits. If you’ve ever panned for gold, you’ve almost certainly panned alluvial gold.

· Alluvial gold is a type of gold that is found in riverbeds, streams, and other water sources. It is formed when gold is eroded from its original source, such as a vein in a rock, and carried by water to a new location.
