Evolution des sols sur les sables d'altération des calcaires gréseux du Lias inférieur dans le sud-est de la Belgique

Auteur :
HERBAUTS, J.

Description :
The forest soils developed in the sandy weathering material of the Liassic limy sandstones in southeastern Belgium have been mapped as argillic brown sands ore, more rarely, as podzolic soils. Chemical and mineralogical analyses make the author to propose that the brownish or slightly podzolised profiles which are developed in the loessic sands of the Liassic cuesta, are the expression of the post-glacial forest pedogenesis, whereas the underlying argillic horizons are probably inherited from a previous phase of soil evolution.
