A sequence of soils is described from a slightly podzolized sandy brown earth to humus-iron podzol. In this gradual degradation sequence morphological and chemical evidence is presented to suggest that the following succession of soil processes is involved: translocation of clay;, chemical weathering of the A, horizon resulting in an association of iron with organic matter, and slight eluviation of iron: the stage of podzol intergrade;, strong iron eluviation: the stage of iron podzol;, eluviation of organic matter, which rests on or is incorporated in a previously developed iron B horizon: the stage of humus-iron podzol. Pollen analysis has helped to establish that podzolization can occur under oak-wood where edaphic environments favour the accumulation of thick, moist, strongly acid organic layers.
