Properties of Alluvial Soils | Hunker

Alluvial soil is rich in minerals and nutrients -- highly fertile, and a good crop soil. It often contains gravel, sand and silt. The chemical content of the soil will depend on where it is located. The topography of the land will influence what runs off into the river that eventually forms the alluvial soil.

Placer deposit - Wikipedia

In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.
