Chemical, physical, and micropedological studies were made of Orthic Black, Orthic Dark Grey, Dark Grey Wooded, and Orthic Grey Wooded profiles developed from relatively uniform glacial till material. The general gradation of morphological properties

Seven termite mounds built by three Macrotermes species (M. michaelseni, M. subhyalinus, and M. herus) at five different sites were studied micropedologically. Construction units and void patterns were considered as integral parts of mound constructi

The nature and distribution of carbonates in calcareous horizons from several Saskatchewan soils were examined micromorphologically. Carbonate minerals were found to occur in several distinct forms which included skeletal grains and plasma, cutanic a

The Ah horizons of a Brown–Dark Brown–Black–Dark Gray–Gray Luvisolic sequence of Canadian grassland and forest soils were studied. Clay-associated humus was present in greater proportions in the grassland than in forest soils, particularly in

The carbonate mineralogy of the Blackstrap Lake sediments in central Saskatchewan indicates that the lake deposits are composed of carbonatic minerals similar to those found in surrounding soils and glacial deposits. Textural differences reflect the

The results of this study indicate the importance of groundwater flow and water table depth on the genesis, characteristics and distribution of soils within a hummocky morainal landscape. Non-saline and non-carbonated soils in upland depressions can
