alluvial gold deposits

Alluvial Gold Explained - To Help You Find Gold

Alluvial Gold (Deposited by water movement) and Eluvial gold (disintegration of rock at the site where it originates - not there through water movement) are essentially primary gold broken down by weathering and erosion and transported by gravity or water movement over many millenia of geological time.
