1.5.1.1 Alluvial deposits (river beds) The soils deposited in riverbeds are known as alluvial deposits. Some textbooks use the term, “Fluvial deposits” for the same thing. The size of particles deposited in riverbeds depends on the speed of flow. If the river flow is strong, only large cobble-type material can deposit. 1.5.1.2 Marine deposits

How are alluvial placer deposits formed?

Alluvial placers are formed by the deposition of dense particles at a site where water velocity remains below that required to transport them further. To form a placer deposit, the particles desired must show a marked density contrast with the gangue material, which is able to be transported away from the trap site.
