A study of a slick spot and associated soils showed the slick spot soil to be characterized by high salts and exchangeable Na throughout the profile whereas the high concentration of salts and exchangeable Na occurred at progressively greater depths in the profile in proceeding from the slick spot into the adjacent associated soils. The clay-size minerals found in both the slick spot soils and the associated soils were illite, montmorillonite, kaolinite, quartz and feldspars. Montmorillonite maxima occurred at progressively lower depths in the profile in proceeding from the slick spot into the associated soils. Partial dissolution studies on the clay-size fraction of the soils showed large amounts of amorphous material with the greatest amount being present in the slick spot soil. It was postulated that this amorphous material together with the high Na content contributed to the impermeability of these soils. /Author/
