Abstract
Mineralogical studies of three profiles from Saskatchewan and two from Alberta showed that the predominant clay minerals were montmorillonite and illite. Some kaolinite was found in the coarse and medium fractions of the clays. The three Saskatchewan profiles were almost identical from a mineralogical point of view. The two Alberta soils differed from these in a few minor aspects such as having slightly more quartz and considerably less feldspars in the silt and clay fractions. Degradation of the montmorillonite in the upper horizons of the Saskatchewan profiles was demonstrated.
