Alluvium is a deposit of eroded materials and sediment that is gathered into one area. As gold and other materials are eroded, the small pieces are pushed by water and other forces into creek and river beds and other depressions. Because gold is heavier than most other naturally occurring materials, it settles at the bottom of these deposits.
