Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river. These are known as secondary (alluvial) gold deposits and they can be worked using a gold pan or cradle. Alluvial gold deposits sparked the Australian gold rushes of the 1850's. Resources

Gold is mainly hosted in alluvial and placer deposits (Mestraud and Bessoles, 1982; Milesi et al., 2006). Primary gold deposits are generally associated with Archean to Paleoproterozoic formations, which are typically hosted in late-tectonic granites associated with quartz veins and dolerite (Mestraud and Bessoles, 1982; Kpeou et al., 2020).
