1985), which has undergone a profound ferrallitic pedogenesis
(Michel 1973; Kalck 1978; Lapparticnt 1985; Diop 1990).
The subsequent in situ alteration of this dust is likely to have played an important role in the pedogenesis
of the agriculturally important soils of the surrounding lower Lachlan valley.
The mineralogical data, characterised by detrital kaolinite and autochthonous pyrite, corroborate the post-burial pedogenesis

on the uplands of the Diamantina Plateau, Minas Gerais, Brazil: a chemical and micropedological study.
In view of contemporary pedogenesis
of Ultisols that does not include desilication and transformation of kaolinite to gibbsite, it is thus difficult to reconcile that these Ultisols would ever be weathered to reach the stage of Oxisols with time as envisaged by Smeck et al.
Nevertheless, based on the limited but realistic appraisals provided by the OSL and TCN examples, it appears that the elevator concept in pedogenesis
must be significantly augmented by other processes that move soil grains within the soil.
This is currently under research at McLeod's Creek so that a clearer picture of ASS landscape pedogenesis
may be obtained.
The soils of B1 are calcareous, drought-sensitive, automorphic soils, corresponding to the Hepatica forest site type , which will probably be the site type formed during the pedogenesis
of former quarry sites .
and soil taxonomy: concepts and interactions.
2013) and may present a large variation in short distances due to diverging pedogenesis
processes (Laliberte et al.
This condition, related to the fact that some soils of the Sao Francisco River Valley present high natural potassium content, provided by the source material and pedogenesis
processes (Cunha et al.
El origen de la acidez es un proceso espontaneo durante la pedogenesis
