Abstract
Maps depicting the regional variation in the chemical and mineralogical composition, and physical properties of tills from throughout the plains region of Alberta were prepared by a computer with an attached plotter. The chemical constituents and properties analyzed and discussed are: copper, zinc, manganese, calcium, boron, molybdenum, cobalt, pH, and soluble salts. The mineralogical components included are clay minerals and feldspars. The physical properties included are particle-size distribution, liquid limit and plastic limit, on the basis of which a number of additional engineering properties were calculated and discussed: plasticity number, plasticity, activity and corrosion potential. Generally, the lithology of the till closely reflects that of the underlying bedrock. A noticeable exception is the distribution of soluble salts, the origin of which is more likely related to groundwater phenomena.
