Definitions for "Colluvium"
Loose, heterogeneous, incoherent mass of soil material and/or rock fragments deposited chiefly by mass-wasting.
Loose deposits of rock debris usually at the foot of a slope or cliff brought there chiefly by gravity (mostly on aslope).
(3) rock and soil accumulated at the foot of a slope from gravitational forces. (4) materials that reached their present positions as a result of direct gravity-induced movement involving no agent of transportation such as water or ice, although the moving material may have contained water or ice. Generally consist of massive to moderately well-stratified, non-sorted to poorly-sorted sediments with any range of particle sizes from clay to boulders and blocks. The character of a colluvial deposit depends on the nature of the material from which it was derived and the specific process whereby it was deposited.
