Colluvium
Colluvium (also colluvial material or colluvial soil; from the Latin colluvio, 'jumbled') is a general name for loose, unconsolidated terrigenous sediments (diamicton) that have been deposited at the base of hillslopes by either rainwash, sheetwash, slow continuous downslope creep, or a variable combination of these processes. Colluvium is typically composed of a heterogeneous range of rock types and sediments ranging from silt to rock fragments of various sizes.
