illuvial

Cutans are a type of illuvial deposit.

The resulting deposits are called illuvial deposits.

Spodic soils refer to a diagnostic subsurface horizon defined by the illuvial accumulation of organic matter.

These constituents may then accumulate to form a spodic illuvial horizon and in some cases a placic horizon or iron band.

"Parabraunerde" is the classification for a brown earth with an elluvial horison above a slightly argillic, clayey illuvial horizon.

Valley grassland and wooded grassland are differentiated by the illuvial soil of the former and the colluvial soil of the latter.

Thus, distinctive, observable morphological features, e.g., illuvial clay accumulation in B horizons, are produced by certain combinations of pedogenic processes operative over varying periods of time.

A duripan is a diagnostic soil horizon of the USDA soil taxonomy that is cemented by illuvial silica into a subsurface hardpan.

Illuvial deposits of clays, oxides, and organics accumulate in subsoil as distinctive soil horizons classified as "B horizons" or "zones of illuviation".

The evidence includes some combination of carbonized roots and rootlets, rhizoliths, illuvial clay cutans, silcrete-like silica cements, and the leaching and alteration of the sandy sediments by weathering and plants.

These soils have eluvial horizons from which clay has been leached after snowmelt or heavy rains and illuvial horizons in which clay has been deposited; these horizons are designated Ae and Bt respectively.

In soil science, eluviation is the transport of soil material from upper layers of soil to lower levels by downward precipitation of water across soil horizons, and accumulation of this material (illuvial deposit) in lower levels is called illuviation.
