Eluvial is an adjective. The adjective is the word that accompanies the noun to determine or qualify it. What is Elluviation in soil science? eluviation, Removal of dissolved or suspended material from a layer or layers of the soil by the movement of water when rainfall exceeds evaporation. Such loss of material in solution is often referred to ...

3. A clay increase (within 30 cm) compared to the above eluvial horizons of: (a) 3% ABSOLUTE greater clay content if the eluvial horizons contain < 15% clay; (b) 1.2 times as much clay if the eluvial horizons contain 15-40% clay; OR (c) 8% ABSOLUTE greater clay content if the eluvial horizons contain >40% clay.
6. Eluviation essentially is a process of removal or "washing out." It plays a crucial role in soil development and is affected by factors like climate, soil type, and vegetation. Illuviation is the complementary "addition" process, which also impacts soil structure, fertility, and overall ecology. The substances involved in both processes ...

In Soil Taxonomy (ST), the argillic horizon is a subsurface horizon that contains "a significantly higher percentage of phyllosilicate clay than the overlying soil material" and "shows evidence of clay illuviation" (p. 10). The thickness requirement ranges between 7.5 and 15 cm, depending on the particle-size class.

Your question is almost a duplicate of What is the difference between eluvium and alluvium?, but you also ask about colluvial deposits.The accepted answer for that question references this convenient guide from the Australian Museum, which also covers colluvial deposits:. Alluvial: Detrital material which is transported by a river and usually …
of deposits: eluvial (derived by in situ weathering or weathering plus gravitational movement), diluvial (scree or talus), colluvial (deposited at the base of slopes by rainwash, sheetwash, slow continuous downslope creep, or a combination of these processes), and alluvial (deposited by rivers). Today, most sapphires are produced from gem ...
