Summary A mineralogical study was made on five geographically associated Solonetzic and Chernozemic soils from the glacial Lake Edmonton basin. The investigation showed that montmorillonite was generally the dominant mineral present in the clay fraction while illite and kaolinite were next in abundance. Chlorite and interstratified clay minerals were present in very small amounts. The montmorillonite was identified as being transitional between beidellite and nontronite types. The high montmorillonite content of the B horizons of all profiles appeared to have resulted from the preferential translocation of this mineral as well as from chemical transformation of other silicate minerals. The light‐mineral analysis showed weathering of feldspars in the sola although no significant differences were noted in the distribution of heavy minerals.
