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
