Gleysols

Gleysols are soils that develop under wet conditions, have a thin (<8 cm) or none at all, Ah horizon and is underlain by a mottle gray or brownish gleyed material. Moss peat that has identifiable plant remains may occur on the surface(Soil Science Glossary, 1978). Water saturated, these soils develop from a lack of aeration(Greenlee, 1981). Gleyed horizons result, colours of dull gray to olive, greenish, bluish-gray develop along with rust-coloured mottles from reduced iron oxides and localized oxidation (Greenlee, 1981).

These soils occur, similar to organic soils, in small depressions and low areas(Greenlee, 1981). In the Peter Lougheed Park, gleysols develop on carbonate rich glacio-fluvial material(Kondla, 1978). Kondla (1978) notes that gleysols are restricted to seepage areas vs. organic soils, which also occur in seepage areas and depression areas. Williams (1990) reports that gleysols are very restricted in the park, to the areas where material thickness retains a continuous ground water supply (McGregor, 1984).
