ILLUVIAL Meaning and
Definition
-
"Illuvial" is an adjective that describes something pertaining to the process of illuviation, which is the accumulation of materials, particularly clays and minerals, in one soil horizon from another through the downward movement of water. Illuviation generally occurs when water-soluble materials are transported from the upper layers of soil and deposited in the lower layers, forming distinct horizons of accumulation.
In the context of soil science, illuvial soil refers to the specific soil horizon where the illuviation process takes place, known as the B horizon. This horizon is characterized by the deposition of clay, iron, aluminum oxides, and other minerals leached down from overlying layers. The illuvial horizon is typically darker and more enriched with nutrients compared to the horizons above, which results from the accumulation of these materials.
Outside of soil science, "illuvial" can be used more broadly to describe any process or phenomenon involving the accumulation or deposition of substances through the movement of liquids or solutes. For example, it may be used in geological or environmental contexts to refer to the formation or deposition of minerals, sediments, or pollutants through the movement of water or other liquids.
In summary, "illuvial" relates to the accumulation of materials, especially clays and minerals, in a lower soil horizon via the downward movement of water.
Common Misspellings for ILLUVIAL
Etymology of ILLUVIAL
The word "illuvial" is derived from the Latin term "illuvies", which means "a washing in". It is composed of the prefix "il-" (meaning "in" or "into") and the verb "luere" (meaning "to wash"). "Illuvies" refers to the process by which materials are washed into or accumulated in a particular region, typically in soil sciences. The term "illuvial" has been formed from this root to describe the accumulation or deposition of materials in a specific soil horizon through illuviation processes.
