What is a colluvium?

Colluvium is a type of soil or sediment that accumulates at the base of slopes due to gravitational processes, such as landslides or soil creep. It typically consists of loose, unconsolidated materials, including rock fragments, soil particles, and organic matter. Colluvium is often characterized by a mixed composition and can vary widely in texture and structure, depending on the source material and environmental conditions. It plays a significant role in landscape evolution and can influence local ecosystems and soil development.
