Related to Laterization: podzolization


Those conditions of weathering that lead to removal of silica and alkalies, resulting in a soil or rock with high concentrations of iron and aluminum oxides (laterite).

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



the process of profound and prolonged weathering of aluminosilicate rocks, leading to the formation of laterites in humid tropical and subtropical climates. It is characterized by intensive removal of silica (SiO2) and bases of Na, K, Ca, and Mg, on the one hand, and the accumulation of oxides of Al, Fe, and Ti in the residual rocks, on the other.

Also, according to Nogami and Villibor (1995), the index e' was designed to evaluate lateritic of non-lateritic behavior of soils and found that lateritic behavior manifests when the result of the analytical formulation of e' is less than 1.15, that occurs when d' >20 and Pi < 100, therefore, cement addition reduce the Pi value to below 100 and increased the d' value up to 20 performing the 'artificial laterization' mentioned above.

Although the reason for this is not clear, some linguists (Chomsky, 1965; Lenneberg, 1967; McNeil, 1966) have attributed this phenomenon to the laterization of the part of the brain that is used for language acquisition.
Briefly, there are three main overlapping processes (ferralitic weathering, latosol formation, and laterization), although they are explained separately for the sake of clearness.
Most of the gibbsite in nature was transformed from K-feldspar and clay minerals during laterization processes, and it is characterized by a small crystal size (Bardossy and Aleva, 1990).
