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.
Soil material, rock fragments, or both moved by creep, slide, or local wash and deposited at the base of steep slopes.
a general term for deposits on slopes or at the base of slopes that have been transported chiefly by mass flow. May be extended to include material that has been transported across surfaces by sheetwash, i.e. flowing water not confined to specific channels.
Transported chiefly by gravity and is unsorted. It may travel within water
sediment deposited by process of rainwash or downhill creep.
A general term applied to any loose, heterogeneous, and incoherent mass of soil material and/or rock fragments deposited by rainwash, sheetwash, or slow continuous downslope creep, usually collecting at the base of gentle slopes or hillsides. (Bates and Jackson 1980.)
A deposit of rock fragments and soil material that has accumulated at the base of steep slopes.
Unconsolidated soil and rock material moved largely by gravity (ie, mass movement), deposited on a lower slope and/or at the base of a slope.
( Ped.). Deposit of rock fragments and soil material accumulated at the base of steep slopes by gravitational action. ( SSSA).
Jumbled, gravity-deposited material found at the base of a slope.
A mixture of soil and angular fragments of rock that have accumulated at the foot and on slopes of mountainsides under the influence of gravity.
Soil that has been transported to its present location by the actions of gravity.
Soil material and/or rock fragments moved by gravity such as during creep, slide, or localized wash-outs, which is deposited at the base of steep slopes.
A loose deposit of rock or soil material at the foot of a cliff or steep slope, that has been transported by gravity.
a general term applied to loose and incoherent deposits, usually at the foot of a slope or cliff and brought there chiefly by gravity. Chatwin et. al
Colluvium is the name for loose bodies of sediment that has been deposited or built up at the bottom of a low grade slope or against a barrier on that slope, transported by gravity. The deposits that collect at the foot of a steep slope or cliff are also known by the same name. Colluvium often interfingers with alluvium (deposits transported downslope by water).
