Oct 17, 2023 · The Alluvium. Alluvium is a loose soil, or sediment, not fused into a rock, formed by erosion, reshaped by water in some form, and redeposited in a riverside setting or by a river. This is suitably represented by the name Alluvium meaning “to wash against”. In simple terms, the soil or sediment deposited or redeposited by continuous erosion ... Most alluvium is Quaternary in age and is often referred to as "cover" because these sediments obscure the underlying bedrock. Most sedimentary material that fills a basin ("basin fill") that is not lithified is typically lumped together as "alluvial".
